Surface Options

See the ultraHD difference

For optimal clarity, FireLite Plus comes in two surface grades, consisting of two pieces of FireLite Premium Grade glass ceramic or FireLite Standard Grade glass ceramic (not available in Obscure). 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. Additionally, FireLite products are manufactured in three distinct surface grades (Premium, Standard and Obscure) that are best reviewed prior to specification. Please contact TGP at 800.426.0279 or to request a sample kit.

 FireLite Standard Grade:
May have slight surface imperfections, which may become more apparent in larger sheet sizes. FireLite Standard Grade is comparable to alternative fire-rated ceramics that are marketed as having a “Premium” finish.

For more information about FireLite surface grades, please see our Premium FireLite FAQ.
 FireLite Premium Grade:
Both surfaces are polished to minimize distortion and provide superior surface quality. FireLite Premium Grade is the industry leader for quality and is unmatched by alternative products or production methods.

Care & Warranty

To maintain aesthetics, it is important to clean the glass during and after construction. For routine cleaning, use a soft, clean, grit-free cloth and a mild soap, detergent, or nonabrasive window cleaning solution.

Rinse immediately with clean water and remove any excess water from the glass surface with a squeegee. Do not allow any metal or hard parts of the cleaning equipment to contact the glass surface.

Failure to comply with these care and cleaning guidelines may result in loss of warranty.
