Minimum Roof Pitch
For
roofs with continuous sheets and no end laps the minimum roof pitch
is 3° (1 in 20). To prevent ponding from occurring this minimum
pitch must be adhered to at all points of the roof. For roofs with
end laps the minimum lap is 200mm for pitches between 3° and
15° and 150mm above 15°. For walls allow maximum end laps
of 100mm. Prior to fixing, turn top end of sheet up and gutter ends
down using the tool available.
Location
of Fasteners at Supports
Insuldeck®
may be fastened to timber or steel suppors by conventional crest
fixing. There should be 5 fixings per sheet at ends and end laps
and 3 fixings per sheet at intermediate supports. Always face side
laps away from prevailing weather.

Side
Lap Fixing
Side
lap fixing may be necessary to maintain a weather proof seal and
secure the overlap especially when the roof is walked on occassionally.
This is best done with either 8 x 12mm self drill stitching screws
or a 3mm blind rivet (rivets should be sealed to prevent penetration.)
Maximum spacing of side lap fasteners should be 900mm for roof sheeting
and 1200mm for wall sheeting. When walking on roofing ensure weight
is distributed in pan only over purlin.
Installation
Care
should be taken not to over-tighten roofing or walling screws as
this may deform the sides of the ribs. Over tightening can also
damage seals of roof screws creating a potential for leaks to occur.
To avoid these problems set screw gun tensions correctly and regularly
review the work as it progresses.
