Bison Glass Floor Tile, 6" x 6" x .1875", White Backed Textured NON-Tempered Glass. Suitable for dry applications. Indoor use only.These tiles are the first dye-sublimation tiles to meet and exceed ASTM tests set forth by ANSI standards for commercial and residential applications. Images are applied to the backside of the glass.These tiles may not be used in any exterior application. Image the non-tempered tile prior to cutting, as pre-cut tile may fracture during pressing. The non-tempered tile may be cut with a glass cutter, or a tile saw (wet saw application, diamond blade). Use a non sand grout specifically formulated for use with glass tile. We recommend CEG-Lite commercial epoxy grout by Custom Building Products, in White. If CEG-Lite is not available, any Epoxy mortar in white will work.
