Fix straining wire by passing it through 5mm holes drilled in the top faces
of the apex/top purlin and the eaves/bottom purlin at 383mm centres. The
wire to pass over the intermediate purlins. The first straining wire to be
fixed 50mm away from gable end. Evenly tension all wire ensuring that cut
ends face downwards.
Roll ALULITE® down the slope of the roof and cut to length with an
additional 200mm of material to use as a grip for tensioning the material.
Fix ALULITE® over the straining wires and ensure that it is laid square
to the building. Attach ALULITE® to the eaves purlin using good quality
double sided adhesive tape of either 24mm width. Firmly grip the top end
of the material and pull to tension the ALULITE® and attach to the apex
purlin again using double sided tape.
All subsequent sheets of ALULITE® to be fixed as above with a minimum
of 100mm overlap over the previous sheet. To achieve the best visual
effect, install ALULITE® starting from the end of the building from where
one wants to see the neatest finish. Straining wires must be positioned at
the centre of the overlaps i.e. not more than 50mm from the edges of the
Lay the roof sheeting as soon as possible after the fitting of ALULITE®.
The insulation properties, tensile strength and ease of handling
makes ALULITE® an ideal and versatile material for use in the
ALULITE® is laid horizontally commencing at the eaves (bottom).
ALULITE® can be laid horizontally or vertically for under sheeting
applications. In the case of Steel Purlins straining wire may be
necessary. Each subsequent layer is then laid with a 100mm
lap over the previously laid sheet. (This ensures that ALULITE®
provides insulation while acting as a waterproofing membrane
and vapour barrier against condensation.)
