Technical Statement
Product Description
Webglas S-996 is a trafficable corrosion resistant fibreglass profiled sheeting, providing its worth in buildings where steel and other roofing or wall cladding materials deteriorate or corrode at an unacceptable rate. The sheet thickness is 2.2mm or 3660grams per square metre and is reinforced with a heavy gauge weaved glass mat which provides continuous strength and protection in every direction. The overall strength is such that wire safety mesh is not required. This is of particular importance in chemically aggressive and corrosive environments where safety mesh can be eroded and traditional steel cladding can quickly deteriorate.
Scope of use
Webglas S-996 is suitable for commercial and retail applications where a trafficable transparent solution is required.
Webglas S-996can be used in buildings where there is a corrosive or aggressive environmental conditions where steel and other roofing or wall cladding materials deteriorate or corrode at an unacceptable rate.
With the choice of transparent or solid colour finishes.
Not suitable for:
Purlin spans are beyond the products capability in relation to the wind pressure.
A fire rating is greater than Group 3.
New Zealand Building Code (NZBC)
The product will, if employed in accordance with the supplier's installation and maintenance requirements, assist with meeting the following provisions of the building code:
- Clause B2 Durability: Performance B2.3.1(b)
The top (weather side) is gel coated with a specially formulated highly
UV resistant resin. This part of the process is identical to Ampelite
Webglas GC premium grade sheeting and provides virtually undiminished
performance for 20 years.
Wonderglas GC (now Wonderglas S-996) has been tested at the Allunga Exposure Laboratory in Allunga QLD, a world renownedtesting facility. All methods of testing are performed to strict Standards. The Altrac system (in which the sample tracks the sun), isgenerally accepted to have a 5 to 1 weathering value. The Wonderglas S-996 result was a light loss of 22% over a period equivalentto 20 years exposure.
- Clause C3 Fire affecting areas beyond the fire source: Performance C3.4(a), C3.7
ISO 5660 Fire testing to achieve a Group 3 in accordance to C/VM2. Fire tests available from Ampelite on request.
- Clause E2 External moisture: Performance E2.3.1, E2.3.2
Surface erosion is eliminated and covered by a 20-year Warranty. Low surface erosion also improves weathering properties. The gel-coated surface provides an almost impenetrable barrier and is warranted against water penetration for 20 years.

Product Criteria
Design requirements
Webglas S-996 is great for commercial and retail applications where a trafficable transparent solution is required. Webglas S-996can be used in buildings where steel and other roofing or wall cladding materials deteriorate or corrode at an unacceptable rate. With the choice of transparent or solid colour finishes, Webglas S-996 can be a solution to a variety of design requirements where steel roofing and other materials are not suitable.
See Scope and Limitations.
Installation requirements
Webglas S-996 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.

Maintenance requirements
This maintenance should include, but not be limited to,
keeping surfaces clean and free from prolonged contact with debris and
moisture. The sheets should be washed at least every 12
months with a soft brush and a mild household detergent, like dish
washing liquid to prevent and remove any dirt build up.
Do
not use spray-on moss and mould type cleaners, or other cleaners that are left
on the surface over time to work.
Avoid chemicals, paint, adhesives and other synthetic
materials as this can also cause damage.
Washers and fasteners should be monitored regularly for
signs of deterioration. This can help prevent any leak points or staining
of the sheeting.
Do not wash with any high-pressure appliance,
such as water blasters, as these can also damage the sheeting.
