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 />

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 />

The system and its components<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 />

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 />

Non-ventilated Kalzip roof<br />

on purlins with trapezoidal inner 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 />

R’w = ~ 38 dB (A)*<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 />

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 />

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 />

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 />

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 />

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 />

Kalzip GmbH offers solar power systems<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 />

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 />

Exacting design calls for creative and detailed<br />

solutions. Today curved corners or<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 />

• stucco-embossed<br />

• AluPlusPatina<br />

• coated material with protection foil<br />

• AluPlusZinc with protection foil<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 />

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 />

General data and characteristics<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 />

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 />

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 />

Design specifications<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 />

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 />

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 />

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 />
