Rooflite Fibreglass

Translucent sheeting is manufactured to match steel roll formed roof sheeting. It can generally be fixed 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 1200mm.

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 cladding.

Rooflite Polycarbonate

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 recommended.

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.
