Specifications

All glass designated on the drawings as fire-rated shall be nominal 3/16" (5 mm) thick FireLite NT supplied by Technical Glass Products. The surface condition shall be either: FireLite NT Premium Grade (both surfaces are polished to eliminate any distortion; industry leader for quality and unmatched by alternative products or production methods); FireLite Standard Grade (may have slight surface waviness or imperfections which may become more apparent in larger sheet sizes; comparable to alternative fire-rated ceramics that are marketed as having a "Premium" finish); or Obscure FireLite NT (patterned surface).

Surface Options

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 SHT at 800.426.0279 or sales@fireglass.com to request a sample kit.

Care

  • Care must be taken not to scratch the film.
  • Do not use bristle brushes or abrasive cleaning materials.
  • Cleaning methods used should be similar to those used on Plexiglas®.
  • A soft cloth or clean synthetic sponge is recommended for washing. Do not use the same
    towel or sponge for wiping sills or frames.
  • A squeegee of 70 - 85 durometer hardness is recommended for removal of wash water
    and dirt from the film.
  • Do not apply heavy pressure in any cleaning operation.
  • Do not leave the film wet.
  • Make sure you use a different sponge, cleaning cloth and water bucket for cleaning the outside and the inside of the windows.
  • A little extra detergent for cleaning the film side will make using the squeegee easier.
