Wonderglas GC®
Premium gel-coated translucent fibreglass sheeting for long-lasting light performance
Wonderglas GC® is Ampelite’s premium-grade gel-coated fibreglass roofing and cladding sheet, designed to deliver exceptional durability, light transmission and UV protection in architectural, commercial, and industrial applications. With a 100-micron UV-resistant gel coat—five times thicker than standard surface films—Wonderglas GC® maintains its clarity, colour and strength for decades, even in demanding outdoor environments.
Unlike standard film-coated or polycarbonate sheeting, Wonderglas GC® resists yellowing, brittleness, erosion, and delamination. Its high-performance construction ensures excellent tensile strength and flexibility over time, making it a trusted solution for projects requiring consistent natural light without performance degradation.
Tested under the harsh UV conditions at the Allunga Exposure Laboratory, Wonderglas GC® retained 78% of its original light transmission after the equivalent of 20 years’ exposure. With decades of proven performance across Australia, Wonderglas GC® sets the benchmark for translucent fibreglass sheeting.
