EXTECH® manufactures skylight, window, canopy and wall systems using a variety of glazing options. These include glass, fiberglass and abuse-resistant cellular polycarbonate (also called polycarbonate structural sheets [PCSS]). PCSS is the fastest growing type of glazing material for both vertical and sloped applications. It is now available in multi-wall extruded sheets which are thicker than insulated glass (and which insulate better). They are also co-extruded with a UV-resistant coating, many of them on both sides. This coating stops 99% of the ultraviolet rays. Thus, it protects the glazing panels and also protects the interiors of your buildings against fading and degradation.
