Introduction
Isola Powertekk is a steel based, light weight roof
covering system designed to provide an attractive and
economic finish for all types of roofs down to 10° pitch.
The Isola Powertekk Nordic tile is manufactured from
0.5 mm cold rolled, galvanized steel and weighs only
7.7 kg/m². The steel thickness combined with the Nordic
profile provides superior strength and stability of the
tiles.
Powertekk Nordic is available in six colours, coated and
covered with mineral granules,
The Isola Powertekk CC is manufactured from 0.45 mm
cold rolled, galvanized steel and weighs only 5.0 kg/m².
Powertekk CC is available in six colours with a hard
and smooth surface. The Powertekk CC coating offers
extremely good colour stability, retention of gloss and
high UV-resistance.
A comprehensive range of accessories is avaliable both
for Nordic and CC, including eaves, ridge, gable end
covers and ventilators, completes the system.
Each tile has a downturned front edge and an upturned
rear edge, and is profiled to provide a strong overlapping
and interlocking roof covering. Powertekk tiles are
produced in large format. This enables faster installation
with fewer fixings compared to traditional tile or slate
roofing.
Once installed Powertekk tiles provide a durable weathertight
and low maintenance roof.
The Installation Manual contains the basic rules for the
correct installation of Isola Powertekk. Compliance with
the following directions will guarantee that your roof is
durable and safe.
Please observe the product and installation differences
between the Powertekk Nordic and Powertekk CC
– especially the differences in the Gable Tiles, and the
difference in batten spacing.

General planning details
NORDIC CC
Roof pitch
The minimum roof pitch for Isola Powertekk is 10° (17.6%).
Minimum allowed roof pitch shall be checked against valid
regulations in each country.
Roof underlay
On roof pitches from 10° to 18° the roof should be built with
a wooden or plywood desk covered with a bitumen based
underlayer. All overlaps must be sealed. On roof pitches above
18° there shall as a minimum be installed a breather membrane
designated for use in supported and unsupported pitched roof
applications, including warm, hybrid and cold roofs.
Ventilation
Metal, and therefore metal roofing, does not permit diffusion.
Correct ventilation will prevent condensation problems. In order
to achieve a functionally correct roof with Isola Powertekk it
is therefore important to ensure satisfactory ventilation of the
space below the tiles. The ventilation shall be arranged to safeguard
a good air circulation from the eaves to the ridge.
Battens and Counterbattens
Counterbattens 30 x 50 mm is recommended. Other dimensions
may be used according to local regulations and good
practice.
Battens 30 x 50 mm is recommended. Standard flashings are
made to fit 30 mm high battens. Where the rafters are widely
spaced, the dimension of the tile battens should be chosen
accordingly to comply with local regulations for load bearing
capacity. Please note that the maximum width of the batten is
65 mm.
Batten distance for Powertekk Nordic shall be 369 mm, measured
from front to front of the battens. For Powertekk CC the
batten distance shall be 371 mm.
Snow load
Powertekk Nordic has been tested for a uniformly distributed
load equal to 21 kN/m² without observing failure or visible permanent
deformations. Isola Powertekk can be assumed to have
adequate strength and stiffness at all relevant snow loads.
Wind load
The pull through or tear out design capasity is 740 N per fastener,
or 7.4 kN/m² with 4 nails per tile. The capasity is adequate
for all relevant wind loads up to hurricane.
4

Safety in case of fire
Powertekk has been tested at roof pitches 15° and 45° according
to the requirements of the DIN 4102, Part 7. Accordingly
Powertekk is classified as resistant against radiant heat and
spread of flames at all roof pitches.
Powertekk also satisfy the requirements for Class B ROOF (t1)
according to prEN 13501-5 regarding surface spread of flames.
Installation temperature
Isola Powertekk can be installed at all temperatures likely to be
met in roofing works. However at temperatures below 0° C
extra care is required, particularly when driving nails and cutting
and bending tiles.
Fixing materials
Appropriate nails or screws shall be used to fix Isola Powertekk
to the battens. Nailing can be done manually or with a nailing
gun.
Metal combinations
Due to the risk of galvanic corrosion copper fixings and mounting
parts must not be used in combination with Powertekk.
Other metal combinations are not a problem.
Cutting of the tiles
The necessary cutting to size should be done "cold" using suitable
hand shears or guillotine shears. Cutting can also be done
by circular saw with a cutting blade specially for this purpose.
Heat-generating cutting with rotating machines faster than
4000 rpm must not be used. Overheating of the metal when
cutting will damage the corrotion protection (zinc) along the
cut edge.
For Powertekk CC sutiable hand shears or guillotine shears are
recommended.
Surface repairs
Surface damages to the roofing should be repaired with the
Powertekk Repair Kit. Details made from lead flashing can also
be colour-matched using the Repair Kit. For correct use of the
Repair Kit see instructions included in the set.
Roof safety
For regular services on the roof (chimney sweeper) safe access
should be planned and built in. Isola TopSec roof ladders,
chimeny platforms and safety hooks are available and custommade
for Powertekk.

CC
The Isola Powertekk roofing system is installed with a constant
batten spacing of:
369 mm for Powertekk Nordic and
371 mm for Powertekk CC.
The spacing shall always be measured from the front of a
batten to the front of the next one.
The first batten at the eave should be placed 20 mm from the
start of the counterbattens.
The adjustment to fit to the total rafter length (“Y”-distance)
is always taken at the ridge. The last batten at the ridge should
be fixed with the upper edge 20 mm down from the ridge.
6

For alternative eaves solutions the first batten is to be placed
at the front end of the counterbatten (see page 11). The
distance from the front of the first to the second batten shall
then be 357 mm.
Covered width and length
NORDIC CC
For calculation of the coverded width of Powertekk tiles including
the Gable Tile or the Barge Board Cover see tables on
pages 27/28.
For easy calculation of the covered length or estimating number
of Powertekk rows from eaves to ridge se table Covered
length on page 29
Installation, roof surface
NORDIC CC
Installation should be done from ridge to eaves, starting with
the second horisontal row from the ridge, which will be the
first row of full tiles. Secure the tiles temporarily left and right
in the top with two nails vertically into the batten. The tiles in
the following rows should be installed with overlaps in a staggered
pattern. The tiles can be laid from right to left - or left
to right. The tiles at the left-hand or right-hand gable should
be cut to fit.
NB: If the tiles have to be cut in the bottom of the profile,
allow approx. 20 mm extra and bend up at the barge board.
7

Y
20mm
Cut the top tile to fit the upper batten spacing “Y” ensuring
that the cut tile rests on the full width of the upper batten.
Secure in top batten with nails. The side overlaps of the tiles
should be staggered to the overlaps in the previously fixed
row.Nail then in the vertical front in every second profile at the
point where the profile is closest to the batten.
NB: If Isola Ridge Ventilation Band is not being used, the top
row of roof tiles should be bent up approx. 20-30 mm at the
ridge. Add this measurement to the length “Y” when cutting.
Subsequent roof tiles should be laid by lifting the front of the
overlying tile. Three or four rows can be prelaid in this way.
The tiles should be fixed in the vertical front part in every second
profile, leaving the lower row unfixed until the following
rows have been placed.
NB: The eaves flashing has to be installed and provisionally
fixed before the eaves row of tiles is placed.

Eaves with Powertekk
Eaves flashing
NORDIC CC
For roofs with underlayer of vapour open membrane, or other
membranes, this should either lead into the gutter via a flashing
or, if the eaves overhang sufficiently, simply to the outside.
The Eaves Flashing is preformed for a roof pitch of 30° and
has to be adjusted to other roof pitches.
The Eaves Flashings are provided with a horisontal cut of 30
mm in one end. Enter the second flashing into the cut and
push together thus ensuring an overlap of 30 mm, secure
temporarily with nails. The eaves flashings will be secured permanently
through the fixing of the bottom row of tiles.
10

Alternative Eaves
NORDIC CC
Roofing underlayer to be taken down over the drip flashing.
First batten to be placed flash with the end of the counterbattens.
Insect prevention net to be fixed to the batten and to the
end of the counterbattens. Eaves flashing to be fixed on top
of the first batten. Front of the second batten to be fixed 357
mm from the front of the first batten.
The bottom row of tiles shall be fixed with screws vertically
close to the edge of the tile. Fix with one screw in every second
small valley and seal around the head of the screw.

The height given is allowing a ventilation gap of 20 mm between
the round ridge and the tiles, based on 30 mm height of
battens both sides. NB: The ridge batten is installed at the correct
heigth (H) above the ridge to support the Round Ridge (Big
or Small). The heigth will vary with varying roof pitches, and
with the chosen ridge element. The Ridge Ventilation Band can
only be installed together with the Round Ridge Big.
11

Ridge with Round Ridge Big
NORDIC CC
Install the ridge batten holder and ridge batten, properly aligned,
at the appropriate height, then fix the Ridge Ventilation
Band. Then fix the spacers for the round ridges 375 mm apart.
NB: The Ridge Ventilation Band is fitted directely over the ridge
batten up to a height (H) of max. 125 mm. Where the height
(H) is greater, an additonal batten over the Ridge Ventilation
Band is required.
When the Isola Ridge Ventilation Band is not used the cut roof
tiles of the top row can be bent up 20 - 30 mm as an alternative.
This measurement has then to be added when cutting the
tiles for the top row.
Capping of the ridge can start from the left or right end of
the roof. Round Ridge single module Start and End pieces are
available. The Round Ridges can then be laid in an overlapping
arrangement and fixed from above at the overlaps.
If a full number of the 3-module Round Ridges do not match
exactly to the ridge length of the roof, it should be used singlemodule
Round Ridges at the last 1 - 2 m adjusting the overlaps
to fit. Alternatively the last piece of Round Ridge should be cut
to fit and formed at the end over the Ridge End Plate.
12

Angle ridge
NORDIC CC
The top row of cut roof tiles to be bent up 20 - 30 mm and
fixed. On both sides of the ridge a batten (max 24 mm thick)
shall be placed parallell to and over the underlying battens
and fixed down into the batten with appropriate nails or
screws. Distance between the overlying battens to be adjusted
to the width of the Powertekk Angle Ridge. Angle Ridge
to be placed with ca 10 cm overlapping and fixed horisontally
into the battens.
Ventilation of the ridge area can be provided through the
installation of Roof Vent 75, or the overlying battens can be
installed in pieces of ca 50 cm with an appropirate gap between
the pieces.
13

Hip
NORDIC CC
The hip capping is identical to the ridge capping. At the eaves
the hip should be closed with a Ridge/Hip end Cap. The tiles
can be bent up approx. 20 mm at the sides of the hip batten
as an alternative to the Isola Ridge Ventilation Band.
The Round Ridges should be cut to fit where the ridge and
hip meet and covered with a Powertekk Y-Ridge 10°-30° or
30°-50°, or the joint should be covered with Isoflex P, which is
the selfadhesive, flexible, granule covered Alu-band for joints.
As an alternative the joint can be covered by lead sheet. The
lead can be matched with the colour of the roof using the
Reapir Kit. The surface to be coated must be free from dust,
grease or oils.
14

Gable with Barge Board Cover
NORDIC CC
25 mm
A barge board is required in order to form the gable. It should
be max. 24 mm thick and shall be fitted 25 mm higher than
the top edge of the tile battens. Installed underlayers should
be dressed up and fixed on the top of the barge board.
Start installing from the eaves. Place the Barge Board Cover
on the barge board and secure from the top and side. The
Barge Board Covers should at the top be covered by the
Round Ridge. The overlapping Round Ridge should be cut in
the area of the cover and bent up to fit.
NB: If the full tiles do not fit exactly to the total length of the
roof the roof tiles must be cut to size accordingly and turned
up approx. 20 mm against the barge board. In the eaves end
the open profile of the Barge Board Cover can be closed. Just
a few straight cuts and bends are required.
15

Gable with Gable Tile
NORDIC
With this type of gable roofing, the roof width must have
exact modular dimensions (see page 27 Table: Covered width
of roof with Gable Tile, Powertekk Nordic).
The barge board shall be mounted with the top at the same
level as the top of the battens.
The Gable Tiles shall be installed parallell with the installation
of the roof tiles. The first Gable Tile (second row from top) to
be placed and fixed temporarily with one nail vertically into
the batten through the prepunched hole.
As the roof tiles are being installed, the Gable Tiles should
each be secured on the side and on the front where they overlap.
16

Gable with Gable Tile
CC
For the installation of Gable Tile CC a barge board shall be
fixed with the top edge to fit against the underside of the tile
battens.
The tile battens to be cut flush with the face of the barge
board. If the tiles have to be cut to fit, allow an extra 10 – 20
mm for bending up.
The Gable Tile CC shall be installed one by one over the ready
installed roof tiles, starting from the eaves. Each Gable Tile CC
shall be fixed on the side with two nails/screws into the barge
board/battens.
17

Valley
NORDIC CC
50 mm
50 mm
150 mm 150 mm
The valley shall be provided with two (counter)battens at each
side. The valley is preformed for 30 mm high battens. These
battens should be laid parallel with the bottom line of the valley
and 150 mm out form the center at both sides. The tile battens
end in the middle of the valley's two battens.
145 mm 145 mm
Fit the Powertekk Valley sections with an overlap of 80 mm
and secure at the side with fixing clips.
NB: The valley sections have a water channel measuring 145
mm to each side and they are tapered towards one end. The
narrow, marked side should be laid towards the eaves.
For continuous support valley boards shall be installed at rafter
level.
18

80 mm
The roughly cut roof tiles should overlap into the valley by
minimum 80 mm from the edge of the installed steel valley.
Use a chalk line to mark a straigth line in correct poisiton (80
mm overlap) and cut along the line.
Of optical reasons the tiles may be bent down along the cut
edges.
Cutting of the tiles
The necessary cutting to size should be done "cold" using suitable
hand shears or guillotine shears. Cutting can also be done
by circular saw with a cutting blade specially for this purpose.
Heat-generating cutting with rotating machines faster than
4000 rpm must not be used. Overheating of the metal when
cutting will damage the corrotion protection (zinc) along the
cut edge.
For Powertekk Nordic the following tools can be recommended:
Festool TS 55 EBQ oder ATF 55 EB
Panasonic EY 3530
19

Chimney flashing
NORDIC CC
Place battens/boards above and below the chimney for support
of the tiles.
Adjust and cut the tiles around the chimney, add 20 - 30 mm
for bending up. The chimney should be flashed with Isoflex
P, then secured and sealed mechanically with a capping strip.
Alternatively the covering can be made with a traditional
flashing. Make sure that the flashing at the back of the chimney
is built up to lead the water to the sides of the chimney.
20

Sidewall flashing
NORDIC CC
The roof tiles should be laid right up to the wall. If a roofing
tile has to be cut to non-modular size, it should be turned up
approx. 20 mm against the wall. The Sidewall Flashing should
be installed from the eaves towards the ridge, then secured
and sealed with a capping strip.
Alternatively Isoflex P can be used as replacement for the
Sidewall Flashing. Shall also be fixed to the wall with a capping
strip and sealed.
21

Front wall flashing
NORDIC CC
Depending upon type of construction ventilation shall be provided
integrated in the construction, or by means of installing an
appropriate number of Roof Vent 75.
The last batten against the wall to be replaced by a board of
thickness 25 mm.
Install Powertekk tiles up to the wall. The last tile to be cut and
bent up 25 mm. Place a batten max 20 mm thick on top of the
upper tile and fix through the tiles into the underlying board.
Install the Front Wall Flashing and fix from the front into the
batten and also fix in top of the vertical part on the wall. Finally
install and seal the Wall Sealing Strip.
22

Installation of accessories
Base plate
NORDIC CC
The Base Plate is used as a basis for fixing of individual steps
and platforms. (The bracket is of make Flender and will fit the
system components from the same producer). It is fixed directly
through the battens using screws. The roof tiles at both sides
overlap the Base Plate. It is fixed in the front by the adjoining
roof tiles. The prefitted bracket should be checked to make
sure that it is firmly attached and the screws tightened if necessary.
The bracket of the Base Plate is limited to roof pitches
between 22° and 55°.
Pipe Penetration Tile
NORDIC CC
For aerials and pipes up to Ø 60 mm. The roof tiles on both
sides overlap the Pipe Penetration Tile. The only fixing in the
front is in the adjoining roof tiles.
23

Roof Vent 75
NORDIC CC
Roof Vent 75 is used wherever constructional ventilation is
not possible. The ventilation opening is 75 cm². The roof tiles
on both sides overlap the vent. The only fixing in the front is
in the adjoining roof tiles.
Sanitary Vent
NORDIC CC
The Sanitary Vent is used to ventilate/extract air from kitchens,
bathrooms etc.. The ventilator is supplied with an insulated
insert, and an adapter for connection to Ø 100, 110, 125,
130 and 150 mm. For roof pitches 10° - 45°.
The roof tiles on both sides overlap the vents. The only fixing
in the front is in the adjoining roof tiles.
24

Soil Pipe Vent
NORDIC CC
The Soil Pipe Vent is used to ventilate the domestic vaste
water pipes. The vent is supplied with a flexible connection
pipe, connecting to Ø 50, 75 and 100 mm.
The roof tiles on both sides overlap the vents. The only fixing
in the front is in the adjoining roof tiles.
Skylight / roof exit
NORDIC
To fit a skylight, leave a “2x4-tile” opening when installing the
roofing tiles. Then insert the skylight. Cut and adjust the downturn
end of the overlying tile row to fit. The window should be
fixed to the rafters at the sides by means of its fixing straps.
25

Installation of roof windows
NORDIC CC
General:
Any make of roofwindow for living areas can be installed in a
Powertekk roof. When using prefabricated flashings, use the
types for normal concrete or ceramic roof tiles (for example
Velux type EDW). The deviations from the manufacturer's
installation instructions only relate to the base, depending on
the system.
When integrating a window, it is vital that the base with its
supports and supplementary timbers are generally placed
directly on the rafter, i.e. the support timbers are arranged
in such a way that the top edge of the support is level with
the top edge of the counter-batten. The support must be no
thicker than the counter-battens used. A width of approx.
15 cm must be available as a support for the prefabricated
flashings.
The window itself shall be fitted in accordance with the
manufacturer’s instructions.
