Description

Webglas S-996 is a trafficable, corrosion-resistant fibreglass profiled sheeting, ideal for use in buildings where steel and other roofing or wall cladding materials deteriorate or corrode at an unacceptable rate.

Available in a choice of translucent or solid colour finishes.

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.

Ampelite Webglas is Living Building Challenge Compliant:

I-13 Red List Declaration Status: LBC Red List Approved
Exceptions: RL-004B - Proprietary Ingredients In Declare
Declare ID - AML-0001
Life Expectancy is 30 years (Warranty: 20 Years)

Key Features

20 year warranty
Standard thickness of 2.2mm has a greater spanning capacity
Additional reinforcing provided by the heavy woven mat construction eliminates the need to install wire mesh below the sheeting
Weave pattern for strong visual appeal
Loss of light transmission after 10 years is just 10% compared to a loss of 30% for standard fibreglass
Very high resistance to yellowing and discolouration
Inbuilt UV protection eliminates 99% of harmful rays
High Impact Resistance – Designed to withstand heavy foot traffic and mechanical impact, making it suitable for industrial and commercial applications.
Chemical and UV Resistance – Provides long-term durability in environments with high exposure to chemicals, salt, and UV radiation
Light Transmission Options – The translucent finish allows for natural light penetration, reducing the need for artificial lighting
Fire Performance – Manufactured to meet relevant fire safety standards for roofing and wall cladding applications
Thermal Stability – Maintains structural integrity across a wide range of temperatures, reducing expansion and contraction issues
Lightweight Yet Strong – Easier to handle and install compared to traditional steel or composite cladding materials
Low Maintenance – Resistant to rust, rot, and degradation, requiring minimal upkeep over time

Scope of Use

Webglas S-996 is ideal for commercial and retail applications where a trafficable solution is required
Can be used in buildings where steel and other roofing or wall cladding materials deteriorate or corrode at an unacceptable rate
Translucent options can be used to provide natural light to interiors

Applications include:

Sky lighting where safety mesh is not desirable such as schools and public buildings
Trafficable roofing where access is required
Corrosive environments such as agricultural & chemical plants, power stations & water treatment, pulp & paper manufacturing
Marine environments

Limitations on Use

Webglas S-996 is not to be used in instances where:
- Purlin spans are beyond the products capability in relation to the wind pressure
- A fire rating is greater than Group 3
In corrosive environments, it is recommended that:
- All fixings are stainless steel
- All fixings are metal profile washers and EDPM seals

In-Service History

Ampelite's Webglas S-996 GC has been utilized in New Zealand since 1995, proving its effectiveness in environments where traditional materials are prone to rapid corrosion. The product's heavy gauge woven glass mat reinforcement provides continuous strength, eliminating the need for safety mesh, which is particularly beneficial in chemically aggressive and corrosive environments. This durability has made it a preferred solution for commercial buildings throughout the country. Additionally, Ampelite's premium grade Webglas S-996, which utilizes the same special resin technology, has been widely used in major projects across New Zealand and Australia, providing low-maintenance roofing and cladding solutions guaranteed for a specific lifetime.

Other Performance Attributes

The product has and can make available the following additional evidence to support the above statements:

Webglas 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 Webglas S-996 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.
AS1562.1: 1992 – Design and installation of sheet roof and wall cladding, Part 1: Metal Concentrated Load Tests. (This code is for metal roofing and is not required for plastic sheeting; however in the interest of safety Ampelite initiated the study). Testsconducted by the CSIRO.
Building, Construction and Engineering in accordance with AS4040.1: 1992, “Methods of testing sheet roof and wall cladding–Part 1: Resistance to concentrated loads”. Report DTS522 dated 24 August 1998 provides details of concentrated loads for various Webglas GC profiles over varying spans.
AS/NZS1562.3: 1996, “Design and installation of sheet roof and wall cladding, Part 3: Plastic”, Section 5.2 “Resistance to windforces”. Limit State Testing for resistance to wind loads has been performed as per the requirements of this standard.
AS4040.2: 1996 “Methods of testing sheet roof and wall cladding – Part 2: Resistance to wind pressures for non-cycloneregions”.Tests conducted by Vipac Engineers and Scientists Ltd. Vipac Report Series 360176_TST_2949_00 dated February to June 2004details varying Webglas GC profiles over varying spans determining strength limit state for non cyclone regions.
Cyclonic Wind Loading Tests: Extensive testing regarding fixings and Webglas GC within cyclonic conditions to 10,000 cycles required for approval within Darwin has also been per-formed. The University of Adelaide EngTest, The Department of Civil & Environmental Engineering details Cyclonic Wind Loading Tests to comply with the requirements of the Building Code of Australia, Northern Territory Annexure.
Will not suffer excessive yellowing and degradation to cause a light transmission loss of more than 25% from the original value when installed, for a period of 25 years from installation.
Will not delaminate, surface erode away, allow protrusion of the reinforcing fibres through the surface, or fracture due to impact from hailstones up to 20mm diameter accompanied by winds of up to 100km/hr, for a period of 20 years from installation.
Will not permit water to penetrate right through the sheet for a period of 25 years from date of installation.
