Alsynite Topglass
Topglass® translucent roofing has been specifically developed to combat the effect of ultra violet rays and atmospheric pollutants without the yellowing and rapid product degradation associated with commonly available glass reinforced roof sheeting. Utilising major technological advances developed by both Alsynite NZ and its suppliers, Topglass® is supplied as a cost effective product encompassing a purpose developed UV stabilised composite resin system and surface protected with an Alsynite proprietary weather surface coating providing longer term effective light transmission providing relevant years of warranty from 15 – 25 years on selected range of products as per catalogue.
