Smart Glass 40

The next product in our line of high-performance glass offerings is a double pane product, which goes by the name SmartGlass 40.  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).  What this means is that a competitor’s room equipped with clear single pane glass will heat up 20% faster than a C-Thru room equipped with SmartGlass 40.  SmartGlass 40 has the same high optical clarity and same visual appearance as ordinary double pane glass; it’s only on a very, very close inspection that one might notice a very subtle green hue.   SmartGlass 40 is so effective that it even outperforms double pane bronze glass by 5%, and without the “dirty” look of ordinary bronze tinted glass.  Other’s bronze double pane glass products also block 23% more visible light than C-Thru’s SmartGlass 40.  While not the highest performing SmartGlass offering, SmartGlass 40 is a smart choice when trying to balance performance with affordability.

            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.
