FireLite® products are a listed ceramic glazing material. FireLite® is available in two different surface conditions for clear viewing, premium grade and standard grade. FireLite® Plus and FireLite NT® are Category II impact safety and can be used where impact safety glazing is required such as for use in doors, sidelites, and other locations where human impact is possible. We can also supply FireLite® products with a Satin Etch when an obscure surface is required.

Because FireLite® is made from transparent glass-ceramic, it differs in color from float glass. FireLite® appears to have a warmer earth tone when compared to the blue green tint of typical float glass. However, like float glass, FireLite® ceramic will not demonstrate a highly perceptible color once installed in a frame.
