Topglass GC SPF is an innovative gel-coated natural lighting product that was developed using Alsynite NZ technology. Topglass GC SPF employs a unique manufacturing process similar to that used in the design and manufacture of modern sunglass eyewear. This makes it the perfect product for New Zealand buildings because of its Solar Protection Feature, which controls roof lighting, prevents heat build-up and harmful UV rays that damage stock and plants.
