Expansion |
|
Always
allow 10 mm expansion gap between ends of planks. Fix from centres
and work outwards. |
|
|
Thermal movement. |
|
Allow a
minimum of 5mm clearance at the end of each 5 metre length of
profile, in order to accommodate expansion. (Foiled 8mm expansion). |
|
|
Windloadings |
|
Maximum
windloading based on 600mm battens spacing. |
|
100mm
cladding... 2000Pa |
|
150mm
cladding... 1350Pa |
|
For
increased wind loadings reduce batten spacings and fixing centres
and check with qualified engineer. As a guide 400mm batten spacings
should be considered for applications over 2 storeys high. |
|
|
Fixing to non
weatherproof substrates. |
|
For
applications involving non weatherproof substrates (e.g. timber stud
wall) a vapour permeable water barrier must be installed behind the
battens and cladding. When used as a decorative facing on
weathertight masonry wall, a watertight barrier is not generally
necessary. The same applies for fixing distances. |
|
|
Caution |
|
Cladding
should not be taken into account when designing a timber stud to
resist racking forces. Do not install cladding at ground floor level
where severe impact will occur. Coloured cladding is not covered
under the 10 year guarantee. |

|
Fixing battens. |
|
Start by
fixing battens to the building framework on top of the permeable
membrane. Battens will also need to be fixed around the periphery of
any openings e.g. a window. |
|
|
 |
|
Vertical Trim |
|
|
Fixing starter trims. |
|
Before
fixing the initial starter trim, make a final inspection of the
building substrate and check if any special consideration needs to
be taken into account with regard to drainage and ventilation. |
|
Work from
a line level, fix the starter trim to the lower timber batten. Use
20mm trim nails. |
|
All
vertical trims should be fixed to perimeter battens. |
|
|
 |
|
Starter Trim |
|
|
Fixing cladding top
finish trim. |
|
Top trims
and trims around windows should be fixed to perimeter battens. Note.
top trim with head drip is also available. (Ref. 1928). |
|
|
 |
|
Top Finish |
|
|
Fixing
internal/external corner trim. |
|
Note. The
same product works as both an internal and external corner trim. Fix
the back half initially and clip the cover on after cladding has
been fitted. |

|
Temperature of use |
|
Profiles
should not be fixed when temperature is below 0 deg. C or above 30
deg. C. Before using profiles, acclimatise them to the temperature
of the workplace. (i.e. do not use warm profiles straight away on a
cold site). |
|
|
Tools. |
|
The
system components are easy to work using normal woodworking tools
for cutting, drilling and shaping. |
|
Handsaws,
use a fine toothed blade. Powertools, use a Carbide tipped blade
with running speeds similar to or preferably higher than those used
for timber. |
|
|
Maintenance |
|
|
Cleaning |
|
Profiles
can be washed with water and mild, non-abrasive detergent. Solvent
based cleaners or cleaning agents containing chlorine should not be
used. Contact with composites based on bitumen should also be
avoided. You can also use our cleaning agent "Decoclean" specially
developed to clean PVC-u products. |
|
|
Painting |
|
Painting
of the product is not recommended. It can cause embrittlement and
dark colours will cause thermal distortion. |
|
|
Repairs |
|
Scratches
are difficult to repair entirely, but they can be polished out using
wet and dry papers. Start with an appropriate grade (180 or 360)
moving down to 1000 grade. Finally polish with a cream cleaner. |
|
|
Sealant. |
|
Use a low
modulus silicone sealant conforming to BS5809. Refer to chosen
manufacturers recommendation. Note. Primers may be necessary when
bonding to certain materials. |
