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, the requirements of the NZ building code and the NZ Metal Roofing Manufacturers’ Association Code of Practice. For full installation details, please download a copy of our installation guide.
Please note these additional important requirements
- Ampelite translucent sheeting matching positive fixed profiles shall be installed using the fastening length applicable to the main cladding, together with a metal profile washer and EDPM seal. This combination creates a secure and weather-tight finish. The fixing screws should not be over-tightened to the extent that the sheet buckles, allowing water penetration at the seal or sheet overlap.
- Fixing should be made at every crest at both ends of the sheet and at every second crest at intermediate purlins.
- Where Ampelite fibreglass sheeting is in contact with safety mesh, an Ampelite purlin protection strip must be installed over the safety mesh to avoid fracturing of the underside of the sheet.
- Where end-lapping of the sheet is required, a minimum of 300mm overlap is essential. Ampelite recommends the use of 25mm 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.
- IMPORTANT: Ampelite sheeting should be installed by pre-drilling oversize holes to allow for expansion and contraction. The basic calculation is 0.75mm per lin. /m, plus shank diameter of the screw. Do not over-tighten screws. EXAMPLE: 10 m sheet – 10 (m) x 0.75 (mm) + 4mm (fastener) = 11.5 mm pre-drilled hole.
- CLIP-FIXED DECKING: 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 two female laps). Fixing of sheets should be carried out in the same manner and practice as those stated for positive fixed profile roofing.
- WALL CLADDING: Pan fixing is required at each girt, and the use of Ampelite grey dome 22mm weather seals ensures a weather-tight seal. Over-tightening or flattening the weather seal must be avoided. Fixing shall occur in every pan at both ends of the sheeting, and at every other pan at intermediate girts.
- CYCLONE ZONE INSTALLATION: 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.

Accessories
Ampelite has a large range of accessories available to help make the installation of Wonderglas S-996 fast and professional. These accessories include a range of self-drilling screws which oversize the fastener holes as they pass through the sheet, and self-adhesive tapes and profiled form filler strips for vermin protection.
Handling, Storage, & Disposal
SL Group 3 Bromine Free Fire Retardant Industrial fibreglass sheeting is a non-trafficable roofing material. The sheeting should always be stored in a dry and fire-safe area and handled with care to avoid damage to the surface coating. Warranties will not apply to sheeting that has been damaged in handling or has mechanical damage as a result of foot traffic.
Fibreglass sheeting is not recyclable and should be disposed of in a landfill. Do not incinerate fibreglass off-cuts as burning produces acrid smoke and noxious, toxic fumes.
Polycarbonate sheeting is recyclable and can be returned to a specialist plastic recycling company or disposed of in a landfill.
Safety Data
There are no ill effects from handling Ampelite fibreglass sheets as a finished product. Some exposure to air-borne particles occurs on the drilling, cutting, and trimming of the material. Although there are no known cases of harmful effects, even after long-term exposure, it is recommended to take certain precautionary steps.
- Eye Contact: Can cause irritation. Appropriate eye protection should be worn. If irritation occurs due to exposure to dust particles, wash eyes with running water using an eye bath or wash bottle. If irritation persists, seek medical attention.
- Skin Contact: Can cause irritation. Shower thoroughly using soap and a cloth or sponge.
- Inhalation: Dust masks are recommended, although particles are not respirable.
- Ingestion: Non-toxic. Extensive studies have revealed no serious effects.
