What is UltraGlasTile? UltraGlasTile is hand-made glass tile. It is available in a multitude of dimensional textures and designs — many of which can be applied to either the bottom surface of the tile (“debossed,”wherein the texture is viewed through the glass) or to the top surface (“embossed, ”whereon the texture is exposed, creating a more tactile and dimensional surface). Tiles are available in 31 standard luminous colors. Custom colors may be specified, for a “color matching” fee. The standard thickness for UltraGlasTile is 5/16”(to more easily interface with 1/4”and 3/8”adjacent materials). Tiles may be specified in greater thicknesses for larger sizes and specific applications.
