Translucent sheeting is manufactured to match
roll formed roof sheeting. It can generally
utilising the same fasteners per AS/NZS 1562.3:1996.
Positive fixed profiles should be
fastened in the rib
or crest of the sheeting in the wall cladding through
the pan or valley. Fasteners should be fixed through
every rib at the end purlins and laps, and alternative
ribs at intermediate purlins. Fasteners for side laps
are recommended for purlin and girt spans exceeding
Rooflite® recommends the use of Weatherlok washers or
similar under the head of each roof fastener. Holes
should be pre-drilled using a sharp metal working bit.
The diameter of the hole should be drilled 5mm larger
than the diameter of the fastener to allow for expansion.
For best results when cutting use a circular saw with
a fine tooth blade, ensuring the sheet is held securely
in place. The use of bulb tite rivets for side lap fasteners
or equivalent is recommended. End laps should be a minimum
of 300mm for roof and 200mm for walls. The use of a
dust mask is recommended.
Safety mesh should be used under all industrial sheeting
installed in roofs, using foam tape or protection strips
to cushion the fibreglass sheet. When stored all materials
should be under cover, in a dry and ventilated area
on a horizontal flat surface. The sheet under no circumstances
is to come in contact with the ground or be exposed
to sunlight during storage.
Fixing specifications should be in accordance with AS/NZS1562.3:
1996 design and installation of sheet roof and wall
Rooflite® Polycarbonate has been specifically designed
for easy and rapid installation. When determining how
to install the sheets, consider the following criteria
to obtain the best results. Fasteners should be secured
without excessive tension that would deform the sheet.
In roofing applications fastening is best through the
crest of the material, for walls fastening through the
valleys. The use of lapseal tape and purlin tape is
All fixings must include a grey domed washer or similar
to prevent seepage of water. When joining sheets, an
overlap of at least one corrugation is recommended.
The upper sheet in the overlap should be upwind. If
an overlap is required on the sheet length we recommend
the minimum of 200mm overlap. All gaskets and sealants
must be compatible with polycarbonate. Consult Rooflite®
Office for recommended sealants for use with our products.
