Physical Properties

Installation

Ampelite sheeting shall be installed in accordance with Ampelite fixing instructions and with AS/NZS 1562.3:1996, Design and installation of sheet roof and wall cladding, Part 3: Plastic. Please note these additional requirements:

Fixing should be made at every crest at both ends of the sheet, and every second crest at intermediate purlins.

Where Ampelite fibreglass sheeting is in CONTACT WITH SAFETY MESH a Protective Foam Strip (75 mm x 5 mm), or a 70 mm Fibreglass profiled Isolation Strip, should be installed over the safety mesh, to avoid fracturing of the underside of the sheet.

Where END LAPPING is required a minimum of 300 mm overlap is essential. On profiles such as corrugated, 5-rib or similar, we recommend the use of 25 mm Lap Seal Tape at the top and bottom edges of the purlin. This ensures the strips are concealed. For Decking profiles, two continuous beads of a clear non-hardening sealer (i.e. silicone), must be applied across the full width of the decking within the overlap. End lapping should only be applied to roofs with a minimum pitch of 5°.

IMPORTANT: Ampelite sheeting should be installed by pre-drilling oversize holes to allow for expansion and contraction. The basic calculation is 0.75 mm per lin./m, plus shank diameter of screw. Do not overtighten screws.

EXAMPLE: 10 m sheet - 10 (m) x 0.75 (mm) + 4 mm (fastener) =11.5 mm pre-drilled hole.

Ampelite sheeting matching clip-fixed deck profiles shall be installed in conjunction with the main cladding and should be side lapped with overlaps on both sides (Ampelite sheets have 2 female laps). Fixing of sheets should be carried out in the same manner and practice as those stated for positive fixed profile roofing.

Pan fixing is required at each girt, and use of Ampelite grey dome 22 mm weatherseals ensures a weathertight seal. Overtightening or flattening the weatherseal must be avoided. Fixing shall occur in every pan at both ends of the sheeting, and every other pan at intermediate girts.

Installation in cyclone prone areas follows the recommendations and code for normal fixing, but further specific requirements must be met. Please contact your local Ampelite office for the latest information.
