Ideal for steel roofing and cladding, Ampelite Perma-Glas resists expansion and contraction for versatile structural design needs.

Thanks to a low coefficient of thermal expansion, Perma-Glas fibreglass sheeting excels in service life when mounted to steel roof cladding.

Combining high strength fibreglass strands with specially formulated resins, Perma-Glas fibreglass panels resist cyclic warping that could result in cracking, deformation and profile alterations around steel purlins and other mounting materials.

Thanks to their corrosion resistance, these roofing sheets are not affected by excessive metal rust or oxidation.

The Perma-Glass series is available in three different levels depending on the service life requirements for various industrial roof panel applications.

Perma-Glas STD – Industrial grade, film coated fibreglass sheet

These reinforced fibreglass panels offer a reliable and economical approach to industrial roofing for commercial businesses.

Specially engineered polyester and vinyl resins are formulated to saturate fibreglass strands during curing, limiting light transmission loss to no more than 30%.

These roofing panels are designed to prevent fibre show over a 5 year period when subjected to harsh weathering and UV surface erosion.

Perma-Glas XL – All-round capable fibreglass panel with upgraded performance characteristics

Engineered for durability in challenging conditions, Perma-Glas XL offers improved light transmission capabilities over a longer life cycle than traditional fibreglass sheeting on rooftops.

Capable of limiting surface erosion, Perma-Glas XL is an ideal choice for industrial businesses and warehouses that require extended structural performance.

Our Perma-Glas XL roofing products resist yellowing and discolouration, backed by a 10 year warranty for light transmission performance.

Perma-Glas Ultra – Ultimate, long-term light transmission capabilities

Perma-Glas Ultra fibreglass sheeting is incorporated with PVF film, providing superior UV absorption, temperature control and highly stable colour retention.

Perma-Glas is exceptionally durable and reliable for warehouses, manufacturing plants and other industrial rooftops.

With Perma-Glas fibreglass roof sheeting, light transmission is optimized for the long term and overall maintenance is minimized once properly installed.

The integrated PVF film resists yellowing and discolouration, thereby keeping facility rooftops looking like new.

Above & Beyond

Perma-Glas Fibreglass Panels Exceed Industry Standards

All Perma-Glass roofing sheets, regardless of performance level, are backed by Ampelite warranties for water penetration and light transmission.

Each panel type conforms to AS/NZS standards and undergoes a rigorous, in-house quality control check.

The roof sheets are manufactured according to the customer’s exact specifications and our products are produced with the very best raw materials and resins on the market today.
