This product consists of an outer pane of 1/8” green glass over an inner pane of 1/8” clear. This new product has 20% lower solar transmission than ordinary double pane clear glass (and 26% less UV transmission). Providing; Eight times the strengh of residential window glass, Ten times the scratch resistants of acrylic windows, and Twice the clarity of other glass types.

* Duralite Tempered Glass is up to:
8 Times Stronger than Residential Window Glass
10 Times More Scratch resistant than Acrylic

            The last two high-performance glass products represent a significant improvement over our old Smart Glass, and are called SmartGlass 60 and SmartGlass 90EZ. Both of these are double pane glass products that incorporate a unique multi-layered low-e coating applied to the inside of the outboard pane of glass.  This incredible coating blocks far higher levels of the sun’s invisible solar heat and harmful UV radiation.
