Introduction<br />
1. Kalzip aluminium roof and façade systems<br />
Kalzip aluminium building envelopes<br />
have been setting trends worldwide in<br />
contemporary building culture for more<br />
than 40 years.<br />
The almost unlimited variety of forms and<br />
the most diverse intelligent additional<br />
functions continually provide architects<br />
and planners with impetus for sophisticated<br />
architecture<br />
More than 80 million square metres of<br />
installed Kalzip profiled sheets speak<br />
for themselves.<br />
Whether for industrial buildings, exhibition<br />
halls, airports, public amenities such as<br />
sports facilities or the renovation of existing<br />
buildings – the outstanding material characteristics<br />
and flexibility of aluminium allow<br />
an inexhaustible variety of forms and offer<br />
durable secure building protection. As a<br />
leading manufacturer of aluminium profiled<br />
sheets, Kalzip offers with this brochure<br />
comprehensive technical information on<br />
Kalzip aluminium roof and façade systems.<br />
Detailed data on the system provide you<br />
with an in-depth insight into the mode of<br />
functioning of this unique building product.<br />
The economical all-in-one solution<br />
In addition to information on the various<br />
material surfaces, colours and refinements,<br />
you will also find valuable design tips as<br />
well as dimensioning tables to support you<br />
during the planning phase. Technical drawings<br />
and installation examples illustrate<br />
the function of the Kalzip system with com -<br />
ponents and accessories, e.g. clips, on<br />
different roof structures. Additive systems<br />
for new buildings or existing building fabric<br />
are described using examples. The Kalzip<br />
Solar <strong>Systems</strong> offer creative freedom with<br />
maximum efficiency for the integration of<br />
photovoltaic systems.<br />

Innovations<br />
2. Kalzip innovations<br />
This page features our new Kalzip products.<br />
Kalzip XT – for a new architectural era<br />
Kalzip XT profiles enable for the first time<br />
the implementation of computer-generated<br />
forms and design principles. Evolutionary<br />
animations, visualised in 3D objects, give<br />
birth to new architectural-organic forms<br />
– the fusion of biology and architecture.<br />
The advantages in summary:<br />
• Horizontal and vertical profiled sheets in<br />
convex and concave forms are possible<br />
• New variations in the design of<br />
geo me tries thanks to XT free-form<br />
profiled sheets<br />
• Small bending radii guarantee the<br />
roofing of unusual building forms<br />
Further information can be found on page<br />
7 and page 28.<br />
The integrated Kalzip renovation<br />
concept – the durable roof renovation<br />
Emergency repairs to the roofs of old<br />
existing buildings are connected with risks,<br />
since expensive consequential damage<br />
can still occur despite that and the costs<br />
can rise dramatically when ‘permanent<br />
building sites’ are the result. The Kalzip<br />
renovation concept for old roofs takes a<br />
new, sustainable path: the sloping roof<br />
with a roof cladding made of aluminium<br />
profiled sheets and adaptation to the latest<br />
thermal insulation standards.<br />
The advantages of the Kalzip<br />
renovation concept:<br />
• Maximum corrosion resistance due to salt<br />
water-resistant aluminium base material<br />
• Permanent, virtually maintenance-free<br />
building protection<br />
• High creative freedom due to individual<br />
roof forms<br />
• No interruption of use during renovation<br />
• Economical, fast installation<br />
The thermal bridge-optimised composite<br />
clip for Kalzip profiled sheets for the<br />
achievement of EnEV 2009-compliant<br />
roof structures<br />
The Kalzip composite clip consists of a<br />
stable steel core, which is encased by a<br />
glass-fibre reinforced plastic.<br />
Advantages of the product:<br />
• Minimum heat transfer enables a roof<br />
structure that is virtually free of thermal<br />
bridges<br />
• Safe load dissipation into the<br />
substructure<br />
• In order to achieve the desired thermal<br />
insulation thicknesses in EnEV<br />
2009-compliant Kalzip roof structures<br />
and to compensate for height tolerances,<br />
the new Kalzip composite clips can be<br />
combined with spacer pads<br />

3.2 Aluminium clip and<br />
thermal barrier pads<br />
Aluminium clip rods can be used for clip<br />
rods, eaves, gutter brackets and fixed<br />
points. The clips must be fixed to a steel,<br />
aluminium or timber substructure. The<br />
clips are attached to the substructure with<br />
the building authority-approved connecting<br />
elements. To connect the profiled sheets<br />
to concrete substructures, spacer structures<br />
made of steel, aluminium or timber<br />
and anchored sufficiently in the concrete<br />
must be placed in-between.<br />

Kalzip 7
The system and its components<br />
Kalzip composite clip<br />
The energy-saving clip for attaching Kalzip<br />
profiled sheets. According to the European<br />
energy-saving directives, which are an integral<br />
part of building regulations in several<br />
countries, it is now obligatory to take<br />
account of thermal bridges when planning<br />
building projects.<br />
The Kalzip composite clip, which is used to<br />
attach the Kalzip aluminium profiled sheets<br />
to the substructure of the roof, fulfills this<br />
requirement in an exemplary manner. It<br />
pre vents thermal bridges and succeeds in<br />
creating a system which is virtually coldbridge<br />
free, therefore optimizing the performance<br />
and efficiency of the roof. This<br />
creates a roof design with heat transfer<br />
coefficients which are entirely determined<br />
by the thermal insulation. All characteristics<br />
and functions relating to the load carrying<br />
capacity and attachment are fulfilled and<br />
are documented in the approval granted<br />
by the German General Bulding Inspectorate<br />
approval. The clip has a PA structure<br />
which is reinforced with steel. E spacer<br />
caps can be connected in between for<br />
varying the required thickness of thermal<br />
insu lation.<br />
In principle, the Kalzip composite clip<br />
type E is attached to the substructure<br />
using the same connecting elements as<br />
those used with the aluminium clip.<br />

Kalzip DuoPlus rotatable clips<br />
and Kalzip DuoPlus rail, perforated<br />
With the development of the DuoPlus rail<br />
and the DuoPlus clip, a solution has been<br />
found which makes the installation of the<br />
attachment elements for Kalzip profiled<br />
sheets even more secure. This solution<br />
significantly increases ease of installation<br />
and further improves thermal insulation in<br />
comparison to conventional roof designs.<br />
(See diagram page 47).<br />
After installing the insulant (d = 100 mm),<br />
the rails are aligned according to the calculation<br />
and mounted with the fastener<br />
systems of SFS intec SD2-S16-6.0 x L in<br />
the steel trapezoidal profile subshell.<br />
Sub sequent ly, the DuoPlus clips are manually<br />
screwed in. Although these remain<br />
adjustable, the DuoPlus rail still offers a<br />
secure hold; therefore DuoPlus 100 can<br />
be adapted to the individual circumstances<br />
depending on the profile dimension<br />
and/or tolerance. Therefore a customised<br />
and convenient installation is guaranteed<br />
every time.<br />

Stucco-embossed Kalzip AluPlusZinc Kalzip AluPlusPatina<br />
3.3 Different finishes and colours<br />
Stucco-embossed surface<br />
The standard version of Kalzip profiled<br />
sheets is stucco-embossed. The robust<br />
stucco embossed finish is created by treatment<br />
with additional embossing rollers.<br />
Due to the special texture of the material<br />
surface, minor dents and accidental damage<br />
is hardly visible. In addition, the surface<br />
diffuses reflected light and minimises the<br />
risk of any dazzling effect.<br />
Kalzip AluPlusZinc<br />
AluPlusZinc from Kalzip GmbH is a fusion<br />
of two of the most established materials<br />
in industry – aluminium and zinc. Manufactured<br />
according to the most stringent<br />
quality standards, this is a technically advanced<br />
product which sets new standards.<br />
It combines stunning aesthetics with the<br />
highest quality materials to achieve design<br />
perfection.<br />
The patented PEGAL process produces a<br />
durable fusion between aluminium and zinc.<br />
An additional surface treatment creates a<br />
stable patina with exceptionally high resistance<br />
to the effects of weathering. Indeed,<br />
tests in accordance with DIN 50017 KFW<br />
(cyclic condensate tests) in addition to HCT<br />
tests have proven that Kalzip AluPlusZinc<br />
out performs conventional zinc surfaces in<br />
terms of resistance to corrosion. This surface<br />
finish creates an appearance of classic<br />
elegance, which makes it ideal for a wide<br />
range of applications.<br />
Kalzip AluPlusZinc offers unique<br />
product advantages:<br />
• Zinc patina with surface protection<br />
• Sophisticated, traditional impression<br />
• Bright surface<br />
• Longevity due to aluminium core<br />
• UV-resistant<br />
Kalzip AluPlusPatina<br />
Special surface treatment of the pre weathered,<br />
stucco-embossed profiled sheets<br />
significantly reduces their natural sheen,<br />
thereby creating a new and attractive design<br />
with a high-quality appearance. With<br />
charac teristics comparable to those of an<br />
aluminium profiled sheet which has been<br />
weathered over years, this elegant and<br />
matt surface pro vides roofs and facades<br />
with impressive style.<br />
The natural ageing process, which the<br />
profile sheets undergo during exposure to<br />
weathering, is not hindered and pro ceeds<br />
in the usual manner. In addition to the new<br />
and attractive surface finish, and the highly<br />
diverse design opportunities which this<br />
creates for planners and architects, Kalzip<br />
AluPlusPatina offers all the product advantages<br />
of the standard, stucco-embossed<br />
design.<br />
Advantages of the product:<br />
• Resistant to weathering and to<br />
aggressive environmental influences<br />
• Considerably less light reflection<br />
• Matt look due to pre-weathered surface<br />
• Decreased glare due to diffuse light<br />
reflections<br />
• Dirt-repellent surface<br />
– insensitive to fingerprints<br />
• Available in a stucco embossed<br />
or smooth finish<br />
• UV-resistant<br />
Coil-Coating<br />
Liquid lacquer is rolled onto the alumi ni um<br />
layer in a coil coating process. These colour<br />
coated coils are then used to roll-form the<br />
Kalzip profiles.<br />
Kalzip profile boards<br />
with polyester coating<br />
The coating is robust and insensitive to<br />
scratching; it has very good forming characteristics<br />
and good resistance to weathering<br />
and UV light. Kalzip profiled sheets<br />
in a polyester execution are mainly used<br />
in locations with normal environmental<br />
influences.<br />
Kalzip profiled sheets<br />
with a PVDF coating<br />
This coating is particularly well suited for<br />
aggressive environments and extreme<br />
climatic conditions, e.g. proximity to salt<br />
water. Profiled sheets with a PVDF coating<br />
are characterised by outstanding UV-resistance,<br />
have very good forming characteristics<br />
and are primarily used for façade<br />
design.<br />
Kalzip ProTect coating<br />
For the protection of the surfaces, Kalzip<br />
additionally offers a high-quality and extraordinarily<br />
weather-resistant special highend<br />
coating on the basis of a polymer<br />
technology using fluorocarbon (FLP). It is<br />
characterised by extremely high resistance<br />
to scratching, maximum colour and gloss<br />
stability as well as considerably higher<br />
surface hardness and temperature resistance.<br />

Kalzip colours<br />
Protective plating<br />
Characteristics of the ProTect coating:<br />
• Available for RAL, NCS and metallic<br />
shades of colour<br />
• Outstanding long-term characteristics<br />
with minimum chalking tendency<br />
• Very good dirt repulsion due to a<br />
Teflon-like behaviour, thus less cleaning<br />
effort necessary<br />
• Resistant to chemicals and also to<br />
aggressive emissions such as aircraft<br />
exhaust gases<br />
• An ‘anti-graffiti effect’ is achieved by<br />
means of the FLP technology and an<br />
additional clear lacquer, offering<br />
effective protection against vandalism<br />
• Also available with high gloss surfaces<br />
• Corresponds to the test conditions<br />
of the Florida test (outdoor storage for<br />
over 20 years)<br />
Colour range<br />
In addition to the diverse range of shape<br />
variants, Kalzip also offers a wide range of<br />
colour and surface finishes which provides<br />
optimum design freedom and safety. Special<br />
colours are available on request.<br />
Controlled colour quality<br />
The aluminium strips coated using the<br />
coil coating process pass through a large<br />
number of elaborate processing steps.<br />
Depending on the type of coating, they<br />
are subjected to different pretreatments<br />
and painted in the desired colour or sealed<br />
with a clear varnish. Aluminium strips with<br />
a single-sided coating are given a coat of<br />
protective varnish on the rear side.<br />
In order to achieve a weather-resistant<br />
and colourfast coating, only high-quality<br />
enamels on a polyester, PVDF or CFTE<br />
basis are used. The coil coating process<br />
is monitored according to the standards<br />
of the ECCA (European Coil Coating Association).<br />
Important criteria here are: colour,<br />
degree of gloss, paint coating thickness,<br />
paint hardness, paint adhesion and ductility.<br />
There are additional long-term tests such<br />
as the acid salt spray test, QUV-B test,<br />
condensation climate in an atmosphere<br />
containing SO 2<br />
and outdoor weathering<br />
tests in an aggressive environment.<br />
Plating<br />
Plated with a special alloy, the aluminium<br />
core is additionally protected. The thickness<br />
of the protective layer is only 4 % of<br />
the material itself. During the rolling process,<br />
a permanent joint between the plating and<br />
the core material is achieved.<br />
The electro-chemical potential of the plating<br />
is lower than that of the core material<br />
and therefore has the effect of a sacrificial<br />
anode in case of exposure to corrosive<br />
agents. Corrosion does not attack the core<br />
material but is limited to the plating. This<br />
protection remains effective even if the<br />
surface of the sheets is damaged.<br />
The performance of the protective plating<br />
has been proved by several tests carried<br />
out by “Bundes anstalt für Materialforschung<br />
und Prüfung (BAM) in Berlin” (German<br />
Federal Institute for material research and<br />
testing).<br />
The advantages in summary:<br />
• Reduced surface reflection compared<br />
to Alu-Natur<br />
• Calm metallic impression<br />
• Salt water resistant<br />
• Even surface greying<br />
• Resistant to weathering and to<br />
aggressive environmental influences<br />
Protective film<br />
At the customer‘s request and/or due to<br />
production requirements, surfaces are<br />
protected against possible damage with<br />
an appropriate film. It must be ensured<br />
that the film is removed within two weeks<br />
of delivery in order to prevent increased<br />
effort for its removal.<br />
Metallic enamels<br />
In the case of metallic enamel coating,<br />
variations in colour may occur between<br />
different production batches. For this<br />
reason it is advisable to take care when<br />
planning facades or visible roofs to make<br />
sure that the profiled sheets are roll formed<br />
from the same batch of material.<br />
Anti-condensation and<br />
anti-drum coatings<br />
If required the profile sheets can also be<br />
fitted with an anti-condensation or antidrum<br />
coating.<br />

Kalzip range of applications<br />
4. Kalzip range of applications<br />
Within the context of the amendment of the<br />
German energy saving regulations (EnEV<br />
2009), the energetic requirements of external<br />
structural components are an important<br />
component of the new energy saving regulations<br />
for improving the sustainable energy<br />
efficiency of buildings in the context of<br />
economic viability and in accordance with<br />
the state of the art.<br />
On the basis of newly-developed materials,<br />
Kalzip system components make a significant<br />
contribution to EnEV-compliant roof<br />
structures.<br />
Application specific system build-up<br />
Kalzip sheets can be used both for ventilated<br />
and non-ventilated roofs as well as<br />
for any roof shape or down to a minimum<br />
pitch of 1.5°.<br />
Furthermore it may be combined with any<br />
kind of support or substructure. The system<br />
depends on the special requirements of<br />
the individual application.<br />
The likely effects of snow, wind, humidity<br />
and weathering are fully taken into account.<br />
Kalzip can easily be configured to provide<br />
the highest levels of thermal insulation.<br />
Thermal insulation requirements can be<br />
easily fulfilled. The thickness of the insulation<br />
can be perfectly adapted to the<br />
individua lrequirements of the building.<br />
In addition, the system offers advanced<br />
detailed solutions for effective interior or<br />
exterior draining of the roof which means<br />
a high degree of reliabilty throughout the<br />
long serviceable life of the roof.<br />
Insulated roof systems are the norm<br />
The main applications for Kalzip roof systems<br />
are insulated roof structures supported by<br />
trapezoidal steel, timber linings, purlins or<br />
concrete elements.<br />
• Chemically neutral, fibrous insulating<br />
materials as specified by e.g. the<br />
German DIN 18 165 are recommended<br />
as suitable thermal insulation. The insulation<br />
is laid into position and is then<br />
compressed to its required final thickness<br />
when are installed the profiled<br />
Kalzip sheets on top. There should be<br />
no cavity between the Kalzip sheets<br />
and the insulation.<br />
• A vapour barrier must be incorporated.<br />
Properly installed it provides the<br />
required air tightness.<br />
• Of course, ventilated roof implementations<br />
are also possible<br />
• The sound reduction values of the<br />
standard roof are subsequently<br />
described. Further improvements<br />
can be achieved by including<br />
additional layers.<br />
• Information on U values can be found in<br />
chapter 7, Kalzip dimensioning tables,<br />
starting from page 47.<br />

Non-ventilated Kalzip roof<br />
on a trapezoidal steel deck<br />
This very economical roof system is used<br />
both for industrial and residential buildings.<br />
In order to make sure that there are no air<br />
cavities under the Kalzip roof skin, compressible<br />
thermal insulation is used. Incorporated<br />
within the roof system the insulation<br />
material is compressed by approx. 20 mm.<br />
The loading on the top skin is not transferred<br />
to the inner skin as an evenly distributed<br />
load but rather at set points via the secret<br />
fixing clips. The design roof load must be<br />
increased by 15 % when dimensioning the<br />
trapezoidal steel sheets. The clips must<br />
be staggered on the inner sheet to make<br />
sure that the load is evenly distributed<br />
across all corrugations of the inner<br />
sheet.<br />

R’w = ~ 35 dB (A)*<br />
Non-ventilated Kalzip roof<br />
on purlins with trapezoidal inner sheet<br />
If the roof is supported on purlins, the inner<br />
sheet has to be oriented parallel to the<br />
top layer. If the module of the inner sheet<br />
does not correspond with the Kalzip elements<br />
a top hat section must be installed<br />
to support the clips. If the Kalzip sheets<br />
can span the existing spacing of the purlins,<br />
the top hat sections will be positioned<br />
on top of the purlins. By this way the inner<br />
sheet carries only the weight of the insu -<br />
lation.<br />
For larger purlin spans additional top hat<br />
sections are required. In this instance, part<br />
of the load needs to be transferred by the<br />
inner sheet.<br />

Non-ventilated Kalzip roof on timber<br />
rafters with visible timber lining<br />
In residential buildings the roof system is<br />
frequently built-up using wooden rafters<br />
with visible timber lining. This is advantageous,<br />
because:<br />
1. there is a clear separation between<br />
the trades of carpenters, roofers etc.<br />
2. a continuous flat vapour barrier<br />
can be installed.<br />
* varies depending on thickness and material qualities<br />
The clips can only be fixed directly in the<br />
timber lining if this has a minimum thickness<br />
of 23 mm. A minimum thickness of<br />
19 mm applies for flat press boards, and<br />
18 mm for OSBs. In both cases the fastener<br />
is visible from below. If the timber lining<br />
is too thin, then a timber purlin must be<br />
installed over the lining and attached to<br />
the rafters. See Kalzip approval No.<br />

fixed using approved dowels (SFS MBR-X-<br />
S4-HX-10x160). The dowels are arranged<br />
alternately in the rails. The distance between<br />
the rails depends on the static calculation.<br />
In the case of slabs made of porous<br />
concrete or non-solid concrete slabs, the<br />
DuoPlus rails are arranged at an angle of<br />
less than 45° to the Kalzip. The dowelling<br />
possibilities must be precisely checked in<br />
each individual case and statically calculated.<br />
The choice of approved dowels must be<br />
matched precisely to the concrete material.<br />

The Kalzip DuoPlus 100 system combines<br />
the advantages of rigid insulation with the<br />
constructional possibilities offered by the<br />
conventional Kalzip roofing system. The<br />
special design is almost cold-bridge free<br />
and has excellent sound absorption properties.<br />
An aluminium rail is placed on the<br />
100 mm thick rigid thermal insulation and<br />
is fixed onto the substructure through the<br />
insulation. Special clips are inserted in the<br />
rail and are adjusted to suit the respective<br />
conditions. Connection of the individual<br />
clips to the rail is not necessary. The patented<br />
and type-tested system consists of<br />
rigid thermal insulation, DuoPlus rail, Duo-<br />
Plus clip and connecting elements to secure<br />
the DuoPlus rail, the compressible heat<br />
insulation and the Kalzip profiles sheets.<br />

The base for the Kalzip DuoPlus 100 is<br />
simply provided by rigid insulation strips<br />
with a width of 24 cm and a thickness of<br />
10 cm. The resulting spaces are filled with<br />
soft heat insulation or low-priced rigid<br />
insulating material. In the case of Kalzip<br />
DuoPlus 100, rigid thermal insulation only<br />
needs to be used in those areas specified<br />
by the statistical requirements. The rigid<br />

soft insulation in all areas where no reduction<br />
in snow loads is required.<br />

Kalzip FOAMGLAS ® System as<br />
a standard and combined solution<br />
This roof design and the system components<br />
used are particularly suitable<br />
for building projects which place high<br />
demands on ensuring that the roof system<br />
is free from condensation and where<br />
there is therefore a permanent risk of<br />
condensation formation. The Kalzip<br />
FOAMGLAS ® System offers a high level of<br />
energy efficiency as the thermal insulation<br />
is airtight and impervious to water vapour.<br />
What’s more, there is no mechanical attachment<br />
between the Kalzip profiled<br />
sheets and the supporting structure. This<br />
means there is no coldbridging. As<br />
FOAMGLAS ® is impervious to moisture<br />
penetration the insulation can also act as<br />
a watertight substructure.<br />
The FOAMGLAS ® slabs are bonded to<br />
different substructures using either a coldbonding<br />
agent or hot bitumen. In order to<br />
attach the composite clips, the galvanized<br />
steel claw plates are inserted under heat<br />
in a fixed installation plan taking into account<br />
the respective roof geometry. The<br />
composite clips are installed on the claw<br />
plates using the recommended fastening<br />
elements. The Kalzip profiled sheets are<br />
installed in the usual manner and are friction-fitted<br />
together. In order to ensure<br />
economic efficiency, the thickness of the<br />
compressible thermal insulation can be<br />
varied. FOAMGLAS ® has a minimum thickness<br />
of 80 mm.<br />
The manufacturer’s installation regulations<br />
are to be observed. The installation and dimensioning<br />
are governed by the Kalzip approval<br />

The corrosion-proof and weather resistant<br />
Kalzip AF aluminium external skin is fixed<br />
with clips in the usual way. How ever, and<br />
this is the distinctive feature of the ProDach<br />
insulation system, rather than being fixed<br />
directly to the substruc ture the skin is<br />
fixed instead to special U-rails embedded<br />
in the insulation material.<br />
The stainless steel system fasteners connecting<br />
the U-rails to the substructure of<br />
the roof penetrate the insulation material<br />
only locally. This almost entirely eliminates<br />
the effect of cold/heat and sound bridging.<br />

This structure is comparable to tradi tional<br />
standing seam systems. It is frequently<br />
used in order to minimise the overall height<br />
of the roof structure. If there is an air gap<br />
under the timber lining adequate ventilation<br />
is essential.<br />
With this in mind, we recommend filling<br />
the total height of the rafters with insulating<br />
material for efficient performance. A vapour<br />

which are perfectly coordinated with Kalzip<br />
for both options.<br />
Kalzip AluPlusSolar<br />
Trapezoidal substructure<br />
Because of the small dead weight and the<br />
lack of structural height, the additional<br />
load on the main support structure remains<br />
very low, which positively affects the costs<br />
of the building. These advantages are par -<br />
ticularly effective in the case of renovation<br />
measures. The problem of the existing<br />
support structure not being able to absorb<br />
additional wind and snow loads, which<br />
frequently arises with crystalline systems,<br />
usually does not arise with Kalzip Solar<br />
systems. The necessary static examination<br />
of the existing building can often be omitted<br />
due to the low loads.<br />
Kalzip AluPlusSolar<br />
The new Kalzip AluPlusSolar profiled sheets<br />
are the first to combine a system of solar<br />
power generation using roof-integrated<br />
photovoltaics with the maximum freedom<br />
of architectural design to create stunning<br />
buildings. The solar laminates are flexible<br />
and extremely durable. Depending on the<br />
particular roof design, they are permanent ly<br />
bonded to straight, convex or concave<br />
Kalzip aluminium profiled sheets. The flexibility<br />
of Kalzip AluPlusSolar can accommodate<br />
barrel vault or monopitch roofs,<br />
as well as customised roof designs.<br />
Kalzip AluPlusSolar is available as a fully<br />
integrated system, including inverter and<br />
accessories, on the AF 65/537/1.0 mm<br />
profiled sheet in RAL 9006 (other colours<br />
available on request). The solar film, available<br />
in two lengths, is laminated in the<br />
factory and then permanently bonded to<br />
the outer surface of the Kalzip profiled<br />
sheets. This film will subsequently generate<br />
the power in the photovoltaic system.<br />
Kalzip profiled sheets which have already<br />
been installed cannot be retrofitted with<br />
laminated solar film. However, existing<br />
Kalzip roofs can be retrofitted with Kalzip<br />
SolarClad. In addition to a roof-integrated,<br />
regenera tive method of energy production,<br />
Kalzip Solar<strong>Systems</strong> also offer the opportunity<br />
of generating energy in the facade.<br />
We can send you detailed information on<br />

The silicon thin-film solar cells use triplejunction<br />
technology to generate more<br />
energy in diffuse light conditions than<br />
crystalline solar cells of the same rated<br />
power and are therefore ideal for use in<br />
European regions. The durability of the<br />
Kalzip profiled sheets and the guaranteed<br />
efficiency of the solar modules now make<br />
it possible to create contemporary, modern<br />
buildings which combine maximum freedom<br />
of architectural design with the integration<br />
of ecological concepts.<br />

silicon (a-Si), bonded onto aluminium system<br />
rails, which can be installed on any<br />
metal roof system in a non-penetrative<br />
manner. These extremely lightweight module<br />
units are suitable for all roof shapes.<br />
Kalzip SolarClad is supplied as a com plete<br />

available in two different lengths, is laminated<br />
onto Kalzip system rails in the factory<br />
to ensure high quality and fast installation.<br />
The solar laminates generate power from<br />
the sun as soon as they are connected.<br />
Kalzip SolarClad is suitable for all roof<br />
shapes with a pitch up to a maximum of<br />
60° from horizontal. As the system is extrem<br />

there are no additional structural requirements<br />
for the roof. Kalzip SolarClad is<br />
therefore suitable for all roof structures<br />

Exacting design calls for creative and detailed<br />
solutions. Today curved corners or<br />
arched roofs can be easily achieved by<br />
advanced industrial prefabrication. They<br />
provide modern industrial architecture<br />
with a high level of functional and aesthetic<br />
quality combined with future oriented<br />
perspectives.<br />

General information<br />
Kalzip AF und AS:<br />
With Kalzip AS and AF profiled sheets, an in -<br />
crease in construction width of up to 20 mm<br />
must be taken into account following curving,<br />
so that an overlap with straight sheets<br />
is not possible.<br />
Smooth-curved Kalzip AF profile sheets can<br />
show signs of increased buckling in the<br />
base plate. As it is impossible for tech nical<br />
production to prevent this buckling, it will<br />
not be accepted as grounds for complaint.<br />
When the optical characteristics of a building<br />
are of increased importance, then<br />
smooth-curved Kalzip AS profile sheets<br />
should be used instead.<br />
Standard:<br />
Constant radius with a short (approx. 400<br />
mm) straight segment at the beginning and<br />
the end of the profile sheet. Any radii below<br />
the standard minimum as well as multiple<br />
radii and/or straight elements in one Kalzip<br />
sheet must be agreed with our technical<br />
department in Koblenz.<br />
It is unavoidable that inter mediate radii occur<br />
in the transition area of different radii as well<br />
as between curved and straight sectors.<br />
Clips must not be located in these areas.<br />
Tolerance limits. Only after consultation<br />
with our technical department in Koblenz.<br />
Special measures are necessary in order<br />
to reach the tolerance limits.<br />
Finish:<br />

• Anti-condensation coating on request<br />
Installation width:<br />
For pre-installed clips:<br />
cover width + 3 mm<br />
successive installation of clips:<br />
cover width + 0 to + 3 mm<br />
Length of profiled sheet:<br />
Minimum length 1.5 m. Shorter lengths on<br />
request. The final overall length depends<br />
on the individual radii and possibility of<br />
transport. Minimum length of segment per<br />
radius = 500 mm.<br />
Transportation:<br />
Maximum loading height 2.4 m. It might be<br />
necessary to coordinate details of transportation<br />
with our logistics department.<br />
Transitional area:<br />
If a Kalzip profiled sheet is roll-curved with<br />
several radii, a transitional area is created<br />
in which no clip may be placed (except a<br />
fixed point clip).<br />
This transitional area can be safely estimated<br />
to be ± 300 mm (600 mm in total) if the<br />
two adjacent radii both have the same sign<br />
has, or ± 600 mm (1200 mm in total ) if the<br />
two adjacent radii have different signs, i.e.<br />
from concave to convex or vice versa. It is<br />
necessary to consult the Application Technology<br />
Dept. in Koblenz for a more exact<br />
determination of this transitional area.<br />

to the cover width (installed width).<br />
Support spacing:<br />
When the supporting spacings are too<br />

Appearance:<br />
The minimum radii outlined above reflect<br />
current experiences. As it is necessary to<br />
curve the profile sheets to the respective<br />
radius, buckling cannot be ruled out.<br />
Installation tip:<br />
It is advisable to provide a support on the<br />
ridge over which the profile sheets can be<br />
curved. Installation should take place from<br />
the direction of the non-covered side.<br />
Packaging:<br />
If the pitch is greater than 1.70 m, then<br />
this information must be supplied when<br />
ordering. The reason for this is that special<br />
packaging may be necessary.<br />

General data and characteristics<br />
5.3 Tapered shapes<br />
Tapered Kalzip profile sheets have become<br />
increasingly significant for roofing appli ca -<br />
tions as they can be formed into a diverse<br />
range of shapes. A roof can offer more<br />
than just protection: it can enable a building<br />
to achieve architectural perfection. In<br />
order to achieve the perfect structure, it<br />
is necessary to take into account several<br />
fundamental considerations. The cover<br />
widths are between 230 and 740 mm. Furthermore,<br />
accessibility is limited.<br />
The bottom sheet must be additionally<br />
supported by rigid insulation. Load distri buting<br />
walkways must be provided. In order<br />
to ensure that the bottom sheet is adequately<br />
rigid, it is essential to incorporate<br />
an eaves angle.<br />
The full surface is always covered with foil.<br />
Anti-condensation coating is only subsequently<br />
available in the spraying process.<br />
Aquasine coating is not possible. Tapered<br />
Kalzip sheets must be installed on the roof<br />
in accordance with the installation instructions.<br />
It is advisable to compare the actual<br />
dimensions of the substructure with the<br />
dimensions stated on the installation instructions<br />
before production in the factory<br />
begins. Larger building tolerances can<br />
require repartitioning of the area which is<br />
to be covered. The tables on the following<br />

5.4 Kalzip XT free-form profiled sheets<br />
Kalzip type 65 /… / 1.0 mm<br />
The XT production technology allows difficult<br />
roof and wall surfaces, even if they are<br />
free-form surfaces, to be clad with Kalzip<br />
profiled sheets. Different radii, convex and<br />
concave, as well as side radii, bulges and<br />
narrowings can thereby be combined in<br />
one profiled sheet.<br />
The limit values are subjected to constant<br />
changes and improvements. The combination<br />
of the various possibilities in particular<br />
has a big influence on the various limit<br />
values.<br />
The following, non-binding limit values<br />
serve as an aid to orientation:<br />
Convex curved 2.50 m<br />
Concave curved 10.0 m<br />
Side radius 20.0 m<br />
Minimum width 275 mm*<br />
Maximum width 740 mm*<br />
The maximum length depends on the<br />
transportation possibilities and the basic<br />
material available. The minimum length<br />
depends on the contour and on the production<br />
procedure and must be examined<br />
in detail.<br />
For reasons related to production, excess<br />
lengths of at least 400 mm are necessary<br />
at the ends of the XT profiled sheets; these<br />
have to be cut off on the building site. They<br />
offer additional flexibility in the alignment<br />
of the profiled sheets.<br />
The quality of the finished Kalzip surface<br />
depends to a large extent on the quality<br />
of the spacer structure between the support<br />
structure and the outer skin. It must<br />
be adjustable in order to be able to compensate<br />
for building tolerances.<br />
The planning and installation of XT profiled<br />
sheets requires a great deal of effort.<br />
XT constructions are planned completely<br />
in 3D. A 3D GUI, preferably in the format<br />
.3dm (Rhinoceros), is necessary for editing.<br />
The suitability of other file formats must<br />
be checked.<br />

5.5 Accessibility/fall arrest systems<br />
For maintenance and cleaning Kalzip<br />
sheets are accessible both during and after<br />
installation without any load distributing<br />
measures. As far as the installation is con -<br />
cerned this will only be valid if the profiled<br />
sheets are zipped on at least one side. The<br />
following table specifies the critical spans<br />
up to which the profiled sheets are accessible<br />
without any additional measures.<br />
It is advisable to install walkways leading<br />
to any units requiring regular maintenance<br />
or operational elements such as daylight<br />
units, chimneys or heating plants. When<br />
exceeding the critical span, load distributing<br />
elements such as wooden planks of<br />
a minium cross section of 4 x 24 cm and<br />
a maximum length of 3 m have to be<br />
installed length – or crosswise over the<br />
Kalzip sheets.<br />
In situations where no rigid thermal insulation<br />
has been installed along the ridge<br />
and eaves areas, the sheets in these parts<br />
of the roof should not directly be walked<br />
on. The reason being that this might lead<br />
to deformation of the flat area of the Kalzip<br />
sheet resulting in a possible accumulation<br />
of rain water.<br />
The last free sheets along the gable end,<br />
single unzipped sheets and of course<br />
translucent panels should not be walked<br />
on. During the installation of the roof any<br />
areas which are frequently walked on or<br />
used for the transport of materials should<br />
be protected by temporary walkways,<br />
which should be secured with seam clips<br />
to prevent them from sliding down.<br />
The Kalzip fall arrest system is a reliable<br />
solution to secure walkways on the finished<br />
roof. It consists of a stainless steel<br />
rope which is fastened to permanently<br />
fixed Kalzip roof anchors and coupled to<br />
the safety harness by means of a guide<br />
link. Project related planning is carried out<br />
by Kalzip GmbH.<br />

Kalzip 29
General data and characteristics<br />
5.6 Material/corrosion resistance<br />
An essential advantage of Kalzip sheets<br />
is the lightness of the aluminium material.<br />
Seawater proof alloys are used as basic<br />
materials.<br />
Protection by natural oxidation<br />
Due to the natural formation of a protective<br />
coat of oxide, Kalzip profiled aluminium<br />
sheets are reliably protected against cor rosion<br />
when exposed to normal weathering<br />
by maritime, continental and industrial<br />
atmospheres. With plated material this<br />
effect is even greater, as the plating acts<br />
as a sacrificial anode protecting the core<br />
material against corrosion for many years.<br />
If, however, the roof is exposed to a highly<br />
aggressive atmosphere occurring in the<br />
immediate vicinity of the building, for instance,<br />
industrial premises such as copper<br />
plants emitting high levels of aggressive<br />
chemicals; appropriate resin coatings with<br />
a minimum thickness of 25 µm will provide<br />
lasting protection.<br />
Protective measures to avoid contact<br />
corrosion are<br />
• plastic coating<br />
• neutralizing the steel surfaces for<br />
instance by hot-dip galvanizing<br />
• interrupting the metallic conductive<br />
contact by applying a primer or by incorporating<br />
a suitable separation layer<br />
Installation in combination with<br />
different materials<br />
Steel:<br />
Direct contact between the profiled aluminium<br />
sheets and unprotected steel parts<br />
of the substructure must be avoided due<br />
to the likely risk of contact corrosion. There<br />
are a number of different protective measures<br />
such as plastic foils, interme diate<br />
layers coated with bituminous, zinc chromate<br />
or chlorinated rubber paint or the<br />
galvanizing of the contact areas of steel<br />
parts.<br />
Timber:<br />
Timber parts in contact with Kalzip should<br />
be dry. For the protection of timber rafters<br />
and other wooden construction elements<br />
in direct contact with aluminium structures<br />
only compatible (f.i. oil based) wood preservatives<br />
must be used. They must not<br />
belong to the group of naphta lenic chlorines<br />
and must not contain any copper, mercury<br />
salts or fluorine compounds.<br />
Concrete and mortar:<br />
Any direct and indirect contact with concrete<br />
and mortar must be avoided. The<br />
concrete/mortar must be set and must<br />
not be damp. As dampness can never be<br />
completely ruled out, it is always advisable<br />
to separate concrete and aluminium<br />
profiled sheets by means of a suitable<br />
intermediate layer. Do not allow drilling<br />
dust to get onto the aluminium surface;<br />
if this does occur, ensure that the dust is<br />
immediately and carefully removed.<br />
Contact corrosion<br />
In contact with other unprotected metals<br />
and under the influence of humidity, aluminium<br />
produces an electrochemical contact<br />
element, which may lead to corrosion.<br />
The annexed table is the result of extensive<br />
tests and investigations carried out in<br />
Sweden and proves that the Kalzip alloy<br />
can be combined with most of the common<br />
materials used for building purposes<br />
without the risk of corrosion.<br />

5.7 Sustainable construction<br />
Aluminium – functional and long-lived<br />
Aluminium contributes substantially to the<br />
effective protection of buildings against<br />
external influences over many years and<br />
to the retention of their value. Kalzip aluminium<br />
roof and façade systems have<br />
been used for 40 years worldwide as a<br />
preferred solution for building envelopes.<br />
One of the outstanding characteristics of<br />
the material is its resistance to weathering<br />
and the associated durability. This result in<br />
security and retention of value, in particular<br />
when high demands are placed on the<br />
use of the buildings e.g. at airports or in<br />
demanding locations, e.g. near the coast.<br />
The material for Kalzip has been submitted<br />
to increasingly critical tests over the course<br />
of the time, including an examination by<br />
the BAM (Federal Institution of Materials<br />
Testing and Research) of the improved<br />
weather resistance of plated Kalzip profiled<br />
sheets after nearly 40 years of exposure.<br />
Sustainable construction with<br />
aluminium building envelopes<br />
The introduction of certification systems<br />
such as Breeam, Leeds and DGNB has<br />
for the first time provided evaluation criteria<br />
for sustainable planning and building,<br />
which urge us to use our resources responsibly<br />
and hence to contribute decisively<br />
to the protection of the environment.<br />
The building and property business in<br />
particular can make a decisive contribution<br />
to the sustainable development of our<br />
society, because around 40 per cent of<br />
worldwide CO2 emissions are caused by<br />
buildings (source: DGNB)<br />
The planning and construction of buildings<br />
will demand integrated solutions in the<br />
future. The entire lifecycle of the building<br />
must be considered. Sustainable construction<br />
aims at a minimisation of the consumption<br />
of energy and resources as well as<br />
the lowest possible impact on the ecological<br />
balance in all phases of the lifecycles<br />
of buildings – from the planning, construction<br />
and use to the renovation and demolition.<br />
All individual measures for the minimisation<br />
of the energy consumption and<br />
use of resources must be optimally coordinated<br />
with one another and external influences<br />
must also be considered.<br />
Sustainable construction means conscious<br />
planning and construction. A comprehensive<br />
quality concept, which is already<br />
applied during product evelopment at<br />
Kalzip, is particularly effective here and<br />
serves both the building industry and our<br />
society. The influence of sustainability is<br />
at its greatest during planning.<br />
The lynchpin of the Kalzip sustainability is<br />
the aluminium itself, a material that can<br />
be recycled any number of times and is<br />
sufficiently abundant: It is the most commonly<br />
occurring metallic element on Earth.<br />
Three-quarters of the aluminium ever produced<br />
is still in use today. Approximately<br />
95% of aluminium from the roof is recycled.<br />
The recycling of Kalzip profiled sheets<br />
and other aluminium products requires<br />
95% less energy than the primary production<br />
from bauxite, without loss of quality.<br />
This avoids approx. 80 million tonnes of<br />
greenhouse gases worldwide per year.<br />

Kalzip 31
General data and characteristics<br />
5.8 Official approvals/design calculations<br />
The use of Kalzip roofing elements is<br />
subject to the official building regulations.<br />
Proof of stability and the suitability for<br />
use must be provided in each individual<br />
case. The basis for the design calculations<br />
is always the German Inspec torate Approval<br />
No. Z-14.1-181 issued by the Institute<br />
for Building Technology. Kalzip is officially<br />
approved by many European building<br />
authorities and is subject to continuous<br />
monitoring.<br />
This includes a description of technical<br />
characteristics, materials and dimensions.<br />
The stipulations for design and measurement<br />
contain information on design loads,<br />
static systems and safety values. The stipulations<br />
on specification govern, amongst<br />
other things, roof pitch, edge design,<br />
accessibility, technical expertise/training<br />
requirements of the installers. The appendices<br />
contain tables relating to standard<br />
details and characteristic values for the<br />
proof of stability and suitability for use.<br />
For frequently recurring applications you<br />
will find load-span-tables, from which the<br />
maximum spans under practical windand<br />
snow loads can be extracted. So the<br />
proof required by law can be easily provided<br />
at any time.<br />
5.9 Transport<br />
When designing unusual special roof<br />
shapes (for instance, long profiled sheets<br />
with small curving radii) the feasablity of<br />
transportation has to be checked with<br />
our logistics department. The dispatch<br />
department at the pro duction factory is<br />
available to advise you here. Permits are<br />
required from the local road authorities<br />
for the transportation of lengths of 18 m<br />
and more. When extreme lengths are to<br />
be transported, it is essential to allow for<br />
the time required to obtain permits from<br />
the local road authorities.<br />
5.10 Sheet thickness<br />
According to the licensing agreement<br />
issued by the building authorities the minimum<br />
thickness for Kalzip profiled sheets<br />
is t = 0.7 mm. Although these sheets are<br />
accessible both during as well as after their<br />
installation for main tenance and cleaning<br />
without the need of load distributing<br />
measures, it is however not advisable to<br />
use sheets of this thickness because of<br />
the risk of denting resulting from people<br />
walking on the sheets during installation.<br />
For aesthetic reasons it is advisable to<br />
choose a minimum sheet thickness of 1 mm<br />
on any visible areas.<br />

6.1 Moisture proof<br />
For insulated roofs and walls it is essential<br />
to provide sufficient protection against<br />
condensation in each and every case. In<br />
this context vapour diffusion (e.g. accor ding<br />
to DIN 4108-3) as well as air flows must<br />
be considered.<br />
Superficial formation of condensate on<br />
structural components<br />
If the minimum values of heat transition<br />
resistance according to DIN 4108-2 are<br />
observed, a verification of the protection<br />
against condensation in non air-conditioned<br />
rooms such as residential premises<br />
and offices is generally not required providing<br />
that these rooms are adequately<br />
heated and ventilated according to the<br />
normal standards.<br />
In special cases for instance with perma -<br />
nent high humidity levels it is necessary<br />
to calculate the required heat transition<br />
resistance in relation to the actual internal<br />
climatic conditions.<br />
Formation of condensate inside<br />
multi-layer constructions<br />
A vapour barrier must be installed in order<br />
to prevent vapour from penetrating from<br />
humid internal rooms into the roof construction.<br />
In wall structures vapour barriers<br />
are generally not necessary.<br />
To prevent humid internal air from diffusing<br />
into the roofing system, an airtight barrier<br />
must be installed, which is fully sealed at<br />
all joints to the adjacent structures, as<br />
required by the Energy Saving Directive.<br />
A professionally fitted Kalzip vapour barrier<br />
meets these requirements.<br />
6.2 Ice barriers<br />
In some regions where exceptionally severe<br />
weather conditions can be experienced,<br />
ice barriers can form on metal roofs with<br />
certain structural features. These are blockages<br />
or plates formed from snow, melt<br />
water or rainwater which have frozen together<br />
and can impede the flow of water on<br />
roofs.<br />
Known regions include:<br />
• the Alpine region<br />
• the Central German Uplands<br />
• other areas which have a high snow fall<br />
Structural features which have led to<br />
ice barriers on roofs:<br />
• Shaded areas created by additional<br />
fitting or structures<br />
• Cold roof overhangs<br />
• Complicated roof shapes, a multitude<br />
of fittings or structures<br />
• Guttering and downspouts which can<br />
freeze up (bends, no gutter heating)<br />
• Accumulated snow, uneven distribution<br />
of snow on the roof<br />
• Linear snow guard systems<br />
• Fall arrest systems with cable<br />
connections<br />
• Lightning conductors<br />
• Walkways<br />
• Discontinuities in the thermal insulation<br />
effect<br />
• Thermal bridging<br />
• Poor workmanship (defective connec<br />
tions on penetrations or roof edges,<br />
defective vapour barriers in the case<br />
of warm interior rooms)<br />
Exceptional weather conditions<br />
experienced in recent winters:<br />
• Rapid and frequent alternation<br />
between freezing/thawing<br />
• Catastrophic snow quantities<br />
• Frost coldness and snow at the same<br />
time<br />
If ice barriers impede or stop the flow of<br />
rainwater or melt water above guttering<br />
there is a risk that the water will accumulate<br />
and enter the attic area and therefore<br />
the building through the joint overlap of<br />
the profiled sheets.<br />
Those areas of the roof which are at risk<br />
include, for example, channels, single-skin<br />
roof overhangs, areas which are partially<br />
roofed and shaded areas.<br />
Standing water must be avoided on metal<br />
roofs. For this reason, these roofs must<br />
always be sloping. This is to prevent the<br />
loading capacity of the roof covering from<br />
being exceeded and the roof from collapsing<br />
as a result of the load exerted by<br />
standing water.<br />
For this reason, the values given in the<br />
standards and in the directives for roof<br />
pitches stipulated by the building authorities<br />
must be observed on all points of a<br />
roof as a minimum.<br />
Furthermore, metal roofs which have longitudinal<br />
and cross joints or overlaps which<br />
have not been welded or soldered, will<br />
not be watertight (against “pressing water”),<br />
but only rainproof. This means that when<br />
accumulated water exceeds a specific level<br />
it will penetrate via the joints and connections.<br />
This is another reason why a minimum<br />
pitch must be maintained.<br />
Standing water on roofs may not only be<br />
caused by inadequate roof pitches but also<br />
as a result of other factors. For example,<br />
as a result of blockages in the flanges on<br />
the profiled sheets which carry the water,<br />
in the case of superstructures or projections<br />
which have been incorrectly designed or<br />
installed or when ice barriers have formed.<br />
An essential planning task is to ensure that<br />
ice barriers are avoided. Various measures<br />
can be recommended. However, no list of<br />
recommendations can be regarded as<br />
complete. As the effectiveness of recommended<br />
measures depends on local conditions,<br />
these measures can only be regarded<br />
as suggestions and do not release the<br />
company carrying out the work from the<br />
obligation to check feasibility. No liability<br />
can be accepted for this.<br />
In view of the experiences of the particularly<br />
catastrophic snow conditions experien ced<br />
in winter 2006, it should be noted that<br />
absolute safety against ice barriers cannot<br />
be guaranteed.<br />
Kalzip 33
Design specifications<br />
6.4 Fire protection<br />
Planning and constructive measures:<br />
• Roof projections should be avoided<br />
or at least insulated<br />
• Shaded areas should be avoided<br />
or heated<br />
• Areas at risk should be equipped with<br />
roof heating<br />
• Substructure should be installed at<br />
least 3 mm towards the inside of the<br />
roof and connected at the gutter<br />
• Flow directions/roof pitch should not<br />
be directed into cold roof areas<br />
• Gutters should be heated, particularly<br />
internal structures<br />
• Bends in downspouts should be<br />
avoided<br />
• Keep downpipes free, service gutters<br />
and downpipes<br />
• Direct gutter heating into the downpipes<br />
right through to the frost-free ground<br />
area<br />
• Be aware of the risk of suspended<br />
gutters breaking away<br />
• Ensure snow remains evenly distributed<br />
on the roof (use a lot of individual snow<br />
guards rather than just a few linear systems)<br />
• Connect vapour barrier to gutter, use<br />
as an emergency downspout?<br />
• Fall arrest equipment, walkways and<br />
other obstacles should be protected<br />
by snow guards to prevent snow and<br />
ice from collecting<br />
• Thermal bridges should be minimized<br />
or completely avoided<br />
• Large discrepancies in U-values should<br />
be avoided.<br />
The planner must check that individual<br />
measures are adequate or whether the combination<br />
of several measures is required in<br />
order to achieve adequate efficiency. If ice<br />
barriers have occurred and these are to<br />
be avoided in the future, then the following<br />
measures can be successful – depending<br />
on the causes. However, there can be no<br />
guarantee of absolute safety here:<br />
• Accumulated snow should always be<br />
removed as quickly as possible. Snow<br />
and ice should be cleared away.<br />
In the case of each of these measures,<br />
the specific conditions of the individual<br />
building in question must always be taken<br />
into account. For this reason, it is not<br />
possible to make general statements.<br />
6.3 Sound absorption<br />
Highly efficient sound absorption can be<br />
easily achieved with Kalzip roofs by constructive<br />
measures such as incorporating<br />
additional layers, while all benefits of the<br />
lightweight constructions remain unaffected.<br />
The demands concerning fire protection<br />
of building materials and structural parts<br />
etc. are specified in the local building regulations.<br />
According to DIN 4102-4 aluminium<br />
alloys are classified in category A1 (”not<br />
inflammable“) without special verification.<br />
Kalzip profiled sheets – even with organic<br />
coatings on both sides and with class B<br />
insulation layers underneath – are classified<br />
as resistant against flash-over and<br />
radiating heat without any special verification<br />
(“hard roof covering“).<br />

6.5 Lightning protection using Kalzip<br />
aluminium profiled sheet envelopes<br />
Economic and efficient protection against<br />
lightning strikes and their effects can be<br />
achieved by using Kalzip systems:<br />
• As a lightning arrest or conducting<br />
device to prevent lightning strikes<br />
affecting the structure<br />
• As a protective screen to counter the<br />
electromagnetic effect of lightning<br />
strikes<br />
When installing Kalzip roof or wall cladding<br />
systems there is generally no need<br />
for dedicated or additional lightning protection<br />
devices. The calculated probability<br />
of structurally damaging lightning strikes<br />
is once in every 500 years. Such a strike<br />
hitting a Kalzip clad building would cause,<br />
at worst, no more than a small hole in one<br />
of the sheet seams. Damage of this nature<br />
would lie above the line of weathering<br />
and could be easily sealed again with<br />
no risk of damage to either the sub-structure<br />
or to the rest of the Kalzip cladding.<br />
Kalzip as a conductor of lightning<br />
According to the lightning protection<br />
standard BS EN 62305-3 or VDE 0185-<br />
305-3 ‘Protection against lightning - Part<br />
3: Physical damage to structures and life<br />
hazard’, metal roofs are suitable as ‘natural<br />
arresters’ for lightning protection.<br />
In the table in Supplement 4 of this standard,<br />
‘Use of metallic roofs in lightning protection<br />
systems’, it is specified that uncoated<br />
metal roofs whose roof elements<br />
(profiled sheets) are connected by folding<br />
(Kalzip foldable aluminium in the finishes<br />
FalZinc and Titansilver) or by flanges (Kalzip<br />
profiled sheets in the finishes stucco<br />
embossed, mill finish, AluPlusZinc or Alu-<br />
PlusPatina) are suitable for use as a natural<br />
component of a lightning protection<br />
system without further requirements.<br />
Roof elements that are bolted or riveted<br />
to one another (trapezoidal and corrugated<br />
profiles) for use with and without an<br />
organic coating are suitable without further<br />
requirements. The same applies to<br />
welded profiled sheets. Type testing is required<br />
if the flanged or folded roof elements<br />
are coated. Kalzip has passed this<br />
examination in accordance with report<br />
BET/Corus 08-06-17-1d issued by the<br />
BET Blitzschutz und EMV Technologiezentrum<br />
- OBO Bettermann, D-58710<br />
Menden.<br />
Hence, roofs made of Kalzip profiled<br />
sheets are suitable without further requirements<br />
for use as a natural component<br />
of a lightning protection system.<br />
The same applies to standing seam roofs<br />
as well as trapezoidal and corrugated<br />
profiles. The prerequisite for this is that<br />
the roofs are capable of conducting current,<br />
e.g. they are connected to ground<br />
via approved lightning conductors from<br />
OBO Bettermann GmbH (www.obo.de).<br />
Technical requirements for lightning<br />
conducting devices:<br />
• The Kalzip sheets must be conductively<br />
connected to earth<br />
• The seams of the Kalzip sheets must be<br />
fully zipped to ensure contact<br />
• There must be conductive connection<br />
of the roof sheets to:<br />
- a conductive wall cladding (metal)<br />
- a steel or aluminium sub-structure<br />
- any concrete sub-structure must be<br />
reinforced<br />
Construction details relating to these<br />
requirements should be checked with<br />
a lightning protection specialist.<br />

Kalzip as protective screening<br />
If the complete building envelope consists<br />
of aluminium (Figure 2 on page 35), i.e.<br />
Kalzip systems used for both the roof and<br />
wall cladding, the envelope will halt and<br />
collect the electrical energy from lightning<br />
and safely conduct it to earth thereby preventing<br />
dangerous voltages from affecting<br />
the power supplies.<br />
IT networks and electronic control systems<br />
connected to the mains power supplies<br />
will be safely protected from damage and<br />
in most instances there will be no need for<br />
additional protective devices.<br />
For optimum screening, the Kalzip profiled<br />
sheets right across the building envelope<br />
should each be con-ductively connected<br />
to earth and any larger openings in the<br />
building should be by-passed. Tests on<br />
Kalzip installations have shown that, depending<br />
on the design of the screening,<br />
the electromagnetic field inside the system,<br />
corresponding voltages and strength of<br />
current, are reduced by a factor of more<br />
than 100.<br />
Technical requirements for protective<br />
screening<br />
• The envelope of the building must be<br />
completely conductive at all points and<br />
connected to earth (Figure 3).<br />
• Kalzip must have a metal finish (stuccoembossed,<br />
AluPlusZinc or mill finish).<br />
• Where coated Kalzip sheets are used:<br />
- the ST Clips must be secured to a<br />
metal substructure<br />
- on timber substructures, the ST Clips<br />
must be connected with aluminium<br />
strips (minimum 60 mm wide and<br />
0.7 mm thick) below the sheeting.<br />
• At the Interface between roof and walls,<br />
each and every profiled sheet must be<br />
connected using short aluminium strips<br />
(minimum 50 mm wide and 1.0 mm thick).<br />
• Window openings should not exceed<br />
1.5 m x 1.5 m. Larger openings must be<br />
by-passed using aluminium strips (minimum<br />
50 mm wide x 1 mm thick) or must<br />
be connected to the wall substructure<br />
by means of aluminium frames, in which<br />
case no other conductive structural<br />
connections are required.<br />
Construction details relating to these<br />
requirements should be checked with<br />
a lightning protection specialist.<br />
6.6 Roof systems<br />
6.6.1 Rafter roof:<br />
Kalzip sheets perpendicular to<br />
the trapezoidal steel deck<br />
A supporting trapezoidal deck forming the<br />
substructure of the roof spans from rafter<br />
to rafter running parallel to the eaves. The<br />
clips are either fixed directly to the top<br />
corrugations of the deck or indirectly by<br />
means of spacers. The fixing points are<br />
visible underneath the supporting steel<br />
deck. The clips are diagonally distributed<br />
on top of the steel deck, so that all corrugations<br />
of the deck are load bearing. The<br />
clips must be located following a special<br />
pattern to ensure even load distribution on<br />
the trapezoidal steel deck both in the case<br />
of positive loads (due to snow) or negative<br />
loads (due to wind or aerodynamic suction).<br />
36 Kalzip
Design specifications<br />
• A continous row of clips is to be<br />
fitted along the ridge and the eaves.<br />
• In between the clips are arranged diagonally.<br />
Distances depend on the design<br />
loads, the Kalzip sheet widths, the pitch<br />
of the ribs and the support spacing of<br />
the trapezoidal sheet underneath.<br />
• The number and positioning of the<br />
clips as well as the joining elements<br />
are indicated in the assembly plan.<br />
• Depending on the likely loads it may<br />
be necessary to halve the spacing of<br />
the clips at the corners and along the<br />
edges of the roof.<br />
(See dimension tables)<br />
6.6.2 Kalzip perpendicular<br />
on timber lining<br />
The clips are fixed directly to the timber<br />
lining. The clips must be positioned on the<br />
timber lining in accordance with positioning<br />
diagram 1 or 2. If the clips are to be positioned<br />
next to each other, then the timber<br />
board and its attachment to the substructure<br />
must be statically verified. A carpentry<br />
attachment is not sufficient.<br />

Determination of wind loads<br />
The wind loads are calculated from the<br />
gust velocity pressure and the coefficient<br />
of the wind pressure. The gust velocity<br />
pressure is determined from the wind load<br />
zone and the height above the terrain<br />
(location and height of the building).<br />
For the coefficient of wind pressure,<br />
distinction must be made between the<br />
roof form, the position on the roof (zone)<br />
and the load induction area. An example<br />
of distribution according to zones is<br />
shown on the right. More exact details for<br />
the determination of the wind loads are<br />
given in DIN 1055 Part 4.<br />

6.6.3 The purlin roof:<br />
Kalzip parallel to inner skin<br />
The clips are fixed to the purlins or the<br />
inner skin spans parallel to the Kalzip<br />
sheet. Depending on the design of the<br />
bottom skin, an inter mediate section may<br />
be necessary with double skin roofs. The<br />
clips are normally positioned on top of<br />
each purlin.<br />
In re-roofing projects with narrow spaced<br />
purlins it may be sufficient to position the<br />
clips on every second purlin only. With<br />
regard to an even load distribution the clips<br />
are alternately arranged on the purlins.<br />
A design calculation is required. Please<br />

6.6.4 Kalzip DuoPlus 100<br />
and Kalzip Duo 100<br />
The Kalzip DuoPlus 100 system always<br />
consists of a full layer of 10 cm thick, rigid<br />
thermal insulation, the DuoPlus rail, the<br />
DuoPlus clip and the special screws for<br />
fixing the rail onto the substructure.<br />
In contrast to this, the Kalzip Duo 100<br />
system does not contain a full layer of rigid<br />
thermal insulation. Strips of rigid insulation<br />
with a width of 24 cm and a thickness of<br />
10 cm are simply inserted under the Kalzip<br />
DuoPlus 100 rails.<br />
In the case of both systems, only the named<br />
components will be permitted. The arrangement<br />
of the rails and the number of connecting<br />
elements are outlined in the installation<br />
plan. The DuoPlus clips are secured against<br />
shifting by means of a plastic strip that is<br />
attached in the factory.<br />
First of all the rigid thermal insulation is<br />
placed on the substructure. A full layer of<br />
rigid insulation is used in the case of Kalzip<br />
DuoPlus 100. Strips of rigid insulation are<br />
used in the Kalzip Duo 100 system and<br />
any spaces between these strips are filled<br />
with soft thermal insulation or rigid insulation.<br />
The DuoPlus rails are then arranged<br />
on the thermal insulation in accordance<br />
with the installation plan and are connec ted<br />
to the substructure through the thermal<br />
insulation.<br />
The special DuoPlus clips are inserted<br />
into the rail and rotated so that they are<br />
positioned parallel to the seam direction<br />
(minimum rotation angle = 45°).<br />
The first row of clips, at the start of the<br />
installation surface (gable end), is aligned<br />
precisely and fixed into the rail by means<br />
of a screw through the base of the clip.<br />
The remaining clips are inserted into the<br />
rail and positioned parallel to the Kalzip<br />
seam direction. Every tenth row of clips is<br />
fixed with a screw to prevent shifting.<br />
The final row of clips, at the end of the<br />
installation surface (gable end), is also<br />
secured into the rail by means of a screw<br />
through the clip base. The compressible<br />
thermal insulation is then placed on top<br />
and pressed over the clips. The Kalzip roof<br />
structure can then be installed as normal.<br />
The DuoPlus rail must be long enough to<br />
cover at least two ribs of the trape zoidal<br />
deck and can be secured in it. If this is<br />
not possible, then a section of adequate<br />
length can be installed next to the first<br />
row (see positioning diagram for rafter<br />
roof and purlin roof).<br />

6.6.5 Kalzip FOAMGLAS ® System<br />
The system always consists of FOAM-<br />
GLAS ® insulating slabs installed and<br />
bonded across the full surface area, the<br />
L-shaped claw plate, the composite clip<br />
with fixing elements and optional compressible<br />
thermal insulation.<br />
No compressible thermal insulation is used<br />
with Kalzip AF; in this case, a PE film is<br />
used as a separating layer.<br />
Kalzip FOAMGLAS ® slabs are available<br />
in different formats and are suitable for<br />
substructures such as:<br />
• steel trapezoidal profiles<br />
• timber lining<br />
• concrete slabs<br />
The slabs are bonded to the substructure<br />
using either a cold-bonding agent or hot<br />
bitumen and the bonding process can be<br />
carried out in an external temperature as<br />
low as +5° C. In lower temperatures the<br />
substructure should be prewarmed accordingly.<br />
In the case of trapezoidal profiles,<br />
bonding is carried out on the upper flanges.<br />
When the substructure is closed, the entire<br />
surface of the FOAMGLAS ® and all joints<br />
are sealed with hot bitumen. The butt<br />
joints of the plates are completely sealed<br />
using the edge dipping process. A hot bitumen<br />
top coat seals the surface and creates<br />
a prepared base for the subse quent<br />
construction work.<br />
In order to attach the Kalzip composite<br />
clips, the newly developed, galvanized<br />
L-shaped steel claw plates are inserted<br />
under heat in a fixed grid, taking into account<br />
the respective roof geometry and<br />
wind/suction load. A friction-fit, cold bridgefree<br />
connection is created with the insulation<br />
layer (in accordance with building<br />
approval Z-14.4-475 issued by the Institute<br />
for Building Technology).<br />
In addition to this, a layer of bitumen with<br />
polyester fleece should also be applied<br />
above the insulation layer and claw plates.<br />
The Kalzip composite clips are installed<br />
on the claw plates using the recommended<br />
fastening elements.<br />
Kalzip AF profiled sheets retain the possibility<br />
of free movement due to a durable PE<br />
film as an isolating layer.<br />

Design specifications<br />
The Kalzip profiled sheets are installed in<br />
the usual manner. When Kalzip AF is used,<br />
the Kalzip backing strip should be used<br />
during welding. Only components which<br />
have been approved by the building authorities<br />
should be used with the FOAMGLAS ®<br />
system. The arrangement of the L-shaped<br />
claw plates and fastening components<br />
(type/no.) is specified in the installation<br />
plan.<br />
Curved roofs<br />
All roof shapes are possible. In the case<br />
of large radii, the insulated slabs are connected<br />
in a polygonal manner or, in the<br />
case of smaller radii and freely shaped<br />
designs, they are delivered already in the<br />
respective shapes or cut to size at the<br />
construction site. The suppliers have a<br />
team of technical advisors who will be<br />
delighted to advise you on these roof<br />
shapes. We recommend that you seek<br />
their advice at the earliest possible stage.<br />
The reference values for the radii (r) are:<br />
r 12 m: slabs installed in a polygonal<br />
manner<br />
(grind edges if necessary)<br />
r 6 m: half slabs installed in a<br />
polygonal manner<br />
r 6 m: special roof shape with<br />
formed parts from factory<br />
FOAMGLAS ® is made from 100% pure<br />
glass and is therefore totally inorganic. It<br />
is manufactured from recycled glass products<br />
and the natural mineral materials<br />
sand, dolomite and chalk in the thermal<br />
foaming process. It contains no CFCs,<br />
flame retardants or binders, does not<br />
release any emissions and does not shed<br />
any fibres.<br />
Fire protection<br />
FOAMGLAS ® is non-combustible and<br />
when used in combination with the fixing<br />
system and the Kalzip aluminium profiled<br />
sheets contributes to wards fire protection.<br />
Fire cannot spread across the foam glass<br />
insulating layer. FOAMGLAS ® insulating<br />
materials, the L-shaped claw plate and the<br />
Kalzip profiled sheets are non-combustible<br />
and as so-called “hard roofing” are resistant<br />
to flying sparks and radiating heat (“fire<br />
from the outside”).<br />
A roof featuring a design made from<br />
FOAMGLAS ® and Kalzip specified by the<br />
manufacturer, is able to meet DIN 18234-1<br />
requirements and can therefore be used<br />
in accordance with the construction stan -<br />
dards for industrial buildings.<br />

6.7 Connections<br />
The Kalzip profiled sheets are connected<br />
to the substructure by clips made of extruded<br />
aluminium. The clips have diverse<br />
holes in the baseplate. Special connecting<br />
elements are used, depending on the<br />
substructure.<br />
Note: The number of connecting elements<br />
depends on the static requirements and<br />
must be determined in each case. At the<br />
edges and corners of roofs as well as at<br />
the edges of walls, the connecting elements<br />
must be dimensioned for increased wind<br />
suction loads. The anchorage depth of<br />
the screws in wooden substructures is<br />
determined according to DIN 1052 T2.<br />
The minimum anchorage depth of the<br />
screw in the wood is 4 x ds. The maximum<br />
accountable anchorage depth is 12 x ds.<br />
(ds = nominal diameter of the screw). The<br />
connecting elements must be made of<br />
stainless steel or aluminium. The use of<br />
galvanised carbon steels is not possible.<br />

Design specifications<br />
6.8 Thermal expansion<br />
Temperature changes can cause length<br />
variations and these must be taken into<br />
account. The thermal expansion coefficient<br />
of aluminium in the observed temperature<br />
range is approx 24 x 10–6/K. When the profiled<br />
sheets are installed at a given temperature<br />
of 20°C, there will be an expansion<br />
in sheet length of approx. 1.5 mm/m in<br />
summer (+ 80°C) and a contraction in sheet<br />
length of approx. 1 mm/m in winter (-20°C).<br />
However, as adjacent components are<br />
also subject to variations in temperature,<br />
and the substructure can usually absorb<br />
elongations, a variation in movement of<br />
± 0.5 mm/m may be applied to the sheet<br />
length in practice. If these requirements<br />
are not fulfilled then the maximum values<br />
stated above must be assumed.<br />
6.9 Design of fixed points<br />
Kalzip aluminium clip /<br />
Kalzip composite clip<br />
The fixed point prevents slippage of the<br />
profiled sheets and is the point of each<br />
Kalzip profiled sheet that is not subject to<br />
a change of length. Each Kalzip profiled<br />
sheet is to be secured at the fixed point<br />
against displacement.<br />
Aluminium clip<br />
Fixed point with<br />
Gesipa PolyGrip<br />
Aluminium-Blind rivet<br />
Ø 4.8 x 10 K9,5<br />
Fixed points are statically verified and<br />
are to be taken from the installation plan.<br />
A hole for the blind rivet is drilled through<br />
the small flange into the head of the clip at<br />
an angle of 45-60° degrees, the rivet is inserted<br />
and the swage head is covered by<br />
the large flange of the next profiled sheet.<br />
Alternatively, the fixed point is manufactured<br />
by the insertion of bolts through the<br />
webs of the Kalzip and the fixed point clip.<br />
Sealing washers must be inserted on both<br />
sides (bolt head and nut). If a composite<br />
clip is used for the fixed point, all drilling<br />
swarf must be removed from the profiles,<br />
since the composite clip is made of plasticsheathed<br />
steel. Rust stains on the profiled<br />
sheets are thus avoided. For the further<br />
installation of the roof surface, the Kalzip<br />
profiled sheets are placed with the large<br />
flange on the small flange, aligned to the<br />
eaves and only then pressed into the next<br />
row of clips.<br />
If the fixed point is not located directly at<br />
the roof ridge, then the elongation of the<br />
Kalzip profiled sheets from the fixed point to<br />
the roof ridge must be taken into account<br />
when forming the covering of the roof ridge.<br />
Each Kalzip profiled sheet may have only<br />
one fixed point. Kinks in the Kalzip profiled<br />
sheet, fixed lighting elements etc. are likewise<br />
fixed points and must be taken into<br />
account. No second fixed point may be<br />
manufactured.<br />
6.10 Ridge, eaves, gable ends<br />
The standard ridge consists of three components:<br />
The ridge closure with its chamber reduces<br />
the wind pressure and at the same time<br />
fixes and protects the foam filler against<br />
UV radiation and birds. The foam filler<br />
acts as an additional “sealing” of the end<br />
of the Kalzip sheet preventing rain water<br />
from pene trating into the system. The folding<br />
up is the final protection against the<br />
ingress of rain water into the ridge.<br />
Generally the ridge is also the place where<br />
the fixed point is located. If the fixed<br />
point is positioned elsewhere, then the<br />
ridge must be designed as a sliding structure<br />
to be able to accom modate the expansion<br />
movement of the profiled sheets.<br />
It is a fact that ventilated ridges cannot<br />
be completely sealed against snow. In<br />
case of high sealing demands or direct<br />
exposure to strong wind additional measures<br />
such as the installation of wind deflector<br />
plates or similar devices will be<br />
neccessary.<br />
At the eaves the drip angle stiffens the<br />
bottom sheet and keeps the eaves filler in<br />
position. On extremely low pitch roofs both<br />
the eaves filler and the folding down of the<br />
bottom sheet ensures that no water can<br />
flow back towards the building. The gable<br />
end is secured by the gable end hook and<br />
the gable end clamping section.<br />
(see page 13).<br />

Welded connecting frame<br />
6.11 Skylights/Smoke/heat extractors<br />
Specially designed soakers are supplied<br />
for the installation of skylights and smoke<br />
extractors, etc.For arched roofs, special<br />
curved soakers are required. The soakers<br />
can either be welded or sealed (in the<br />
case of a minimum roof pitch of 2.9°) into<br />
the roofing. Welding is the recommended<br />
option.<br />
The steel soaker is securely connected to<br />
the substructure. The vapour barrier is installed<br />
on the soaker and extends up to<br />
the height of the thermal insulation. The<br />
covering frame is either welded or sealed<br />
to the Kalzip sheets and is able to move<br />
with the Kalzip roof skin. The upper con necting<br />
frame securely connects/seals the sky -<br />
light or smoke extractor in the roof skin.<br />
Skylights and smoke extractors must not<br />
be walked on. As these must be regularly<br />
accessed for servicing and maintenance<br />
work, it is recommended that the area<br />
around the opening is reinforced with rigid<br />
thermal insulation. Large lighting elements<br />
or rows of sky lights can require special<br />
solutions and must be planned in detail.<br />
6.12 Transverse joints<br />
It is not always possible to produce the<br />
required Kalzip sheet length in one element.<br />
In most cases the length of the sheets is<br />
determined by transport limitations, so that<br />
the sheets must be joined by overlapping.<br />
Especially with arched roofs the maximum<br />
loading height of the trucks must be observed.<br />
Obviously, the requirements for absolute<br />
tightness of the overlapping joints are<br />
very high. Therefore it is necessary to take<br />
great care when making over lapping joints.<br />
Overlaps are positioned on top of the support,<br />
if the joint is located at the fixed point.<br />
Otherwise the profiled sheets have to be<br />
joined directly next to the support. Joints<br />
can be either welded or sealed.<br />
Welded joint<br />
The Kalzip profiled sheets to be joined are<br />
overlapped by approx. 10 - 20 mm. The<br />
welding seams should be supported.<br />
The structure underneath the welding seam<br />
must be secured against fire, e.g. by means<br />
of the Kalzip welding underlay. Welding<br />
seams must maintain a minimum distance<br />
of 100 mm to the Kalzip composite clip in<br />
order to avoid the clip being damaged by<br />
heat. If necessary, the fire brigade must be<br />
informed before carrying out welding work.<br />

Design specifications<br />
Sealed joints<br />
(only possible with minimum roof pitch of 2.9°)<br />
The profiled sheets are installed in a precise<br />
sequence according to the assembly in struc -<br />
tions. The critical tightness of seal is achieved<br />
by three rows of silicone in the joint zone of<br />
the individual profiled sheets plus two rows<br />
of sealing rivets. The overlap is 200 mm.<br />
Kalzip and the substructure, the thermal<br />
barrier pads under the clips provide sufficient<br />
separation.<br />
On concrete substructures a suitably<br />
anchored steel section or timber batten<br />
(minimum thickness 40 mm) must be<br />
inserted.<br />

with table<br />
In this kind of design a short clip piece can<br />
be installed within the seams to secure<br />
the gutter support. The clip is attached by<br />
using either 2 rivets in the clip head or 2<br />
screws. As there is no connection to the<br />
substructure, the Kalzip profile sheets are<br />
able to expand freely. With a sheet length<br />
of greater than 12 m the downpipe must<br />
be designed to accommodate the elongation<br />
of the tracks, e.g. by means of moveable<br />
pipe laps. The sheets must be connected<br />
with the eaves angle in each case.<br />
Please note:<br />
The roof projections are not accessible<br />
during installation or before the seams are<br />
zipped. Please observe and follow all instructions<br />
relating to safety measures and<br />
fall arrest equipment. Roof projections<br />
should be fitted with clip bars in the case<br />
of values above 1.0 and up to 1.5 m.<br />
The roof projection (a) is calculated from<br />
the spacing between the first clip at the<br />
roof edge and the outer edge of the Kalzip.<br />
