Wonderglas GC - Industrial Fibreglass Roofing & Skylights

Overview
Ampelite introduced Wonderglas GC gel coated sheeting to New Zealand in 1995 expressly to combat our very harsh environments. Wonderglas GC continues to be a preferred solution for commercial buildings throughout the country. Wonderglas GC is recommended for commercial and retail applications where excellent long term light transmission is required.

Wonderglas GC is often referred to in a number of other ways such as fibreglass roofing, sky lights and sky lighting; Wonderglas clear sky lights, Fibreglass sheeting and plastic sky lights; Tinted sky lighting, sky lights; Clear fibreglass sheets, sheeting; Tinted  fibreglass sheeting, sheets.

History of Fiberglass in New Zealand.
Fiberglass has been used in New Zealand for over 50 years as a cost-effective sky-lighting material. Unfortunately, fiberglass has often been overlooked in many applications due to perceptions of poor translucency, high levels of yellowing, and poor aesthetics associated with surface erosion (known as “fiber show”). In New Zealand, fiberglass sheeting has traditionally been protected by surface films. These films are layered on to the sheet during manufacture, and are designed to be “self sacrificial”. Unfortunately, most surface films have poor weather ability, and have been known to delaminate in as little as 3 years! More recent surface films containing high-level UV stabilizers have improved performance and weather ability; however testing has shown their life-span to limited.

Wonderglas GC features a 25 year warranty

WHAT IS GEL COAT?
Gel Coats have been used in many applications, ranging from truck bodies, to swimming pools and yachts. Ampelite are now able to apply this superior method of fiberglass protection to a range of fiberglass cladding materials!

WONDERGLAS GC – Proven Performance
Ampelite uses the superior Silmar S-996 Gel Coat on all Wonderglas GC product. Silmar S-996 was specifically designed as a clear Gel coat for roofing. This highly UV resistant Gel coat provides Wonderglas GC with the ultimate  impenetrable barrier that reduces surface erosion and loss of light transmission to negligible proportions. Since its introduction, Wonderglas GC has been proven on thousands of installations throughout New Zealand.

Unchanged

The composition of our Gel coat and the basic manufacturing process has not changed since Wonderglas GC’s introduction into the New Zealand market in 1995, making it the oldest and most dependable Gel coated roofing sheet in the market.
■ Surface erosion (fibre show) is eliminated.
■ Superior resistance to yellowing and hazing.
■ Minimal loss of light transmission over life.
■ 99% protection from UV rays.
■ More cost effective over the life of the building.

Testing and Evaluation

Wonderglas GC has been tested at the Allunga Exposure Laboratory in Allunga QLD, a world renowned testing facility. All methods of testing are performed to strict Standards. The Altrac system (in which the sample tracks the sun), is generally accepted to have a 5 to 1 weathering value. The Wonderglas GC result was a light loss of 22% over a period equivalent to 20 years exposure. The test samples still displayed a very smooth, glossy surface with no fibre show at all.

The CRC (Cooperative Research Centres Program) of Australia is a Government Program who’s Participants include:

  • Aust Nuclear Science & Technology Org
  • CSIRO Building, Construction & Engineering
  • Monash University, Materials Engineering
  • RMIT University, Polymer Technology Centre

The CRC Performed a Study on “Weathering of Glass-Reinforced Roof Sheeting Materials”. The study examined resin types, glass size and content, coatings of fibreglass sheeting commercially available in Australia. The results were published in August 2000:
“The standard orthophthalic resin with the BP gel coat was the most weather-resistant system to use. The BP gel coat was the most durable of all the coatings trialed and showed superior weather ability compared to those coatings currently being used in industry”.

Accessories
Ampelite have a large range of accessories avialiable to help make the installation of Wonderglas GC quick and professional. These accessories include a range of self-drilling that oversize the fastener holes as they pass through the sheet and self-adhesive tapes and profiled form filler strips for vermin protection.
Please download our Accessories and Fixings page.


Fibreglass Teks. Fixing fiberglass sheeting to steel purlins

Correct installation is important

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 Manufactures 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 gives a secure and weather tight finish. The fixing screws should not be over tightened to an 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 every second crest at intermediate purlins.
  • Where Ampelite fiberglass sheeting is in contact with safety mesh a 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 300 mm overlap is essential. Ampelite 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.
  • 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 over tighten screws. EXAMPLE: 10 m sheet - 10 (m) x 0.75 (mm) + 4 mm (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 2 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 use of Ampelite grey dome 22 mm 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 every other pan at intermediate grits.
  • 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.

Handling, Storage & Disposal
Wonderglas GC Industrial Fiberglass 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 as warranties will not apply to sheeting that has been damaged in handling, or mechanical damage as a result of foot traffic.
Fiberglass sheeting is not recyclable and should be disposed of in a land fill. Do not incinerate fiberglass off-cuts as burning produces acrid smoke and noxious, toxic fumes.

Safety Data
There are no ill effects from handling 'Ampelite' Fiberglass sheets as a finished product. Some exposure to air borne particles occurs on drilling, cutting and trimming of the material. Although there are no known cases of harmful effect, 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.
