The types of glass tile depend on the temperature at the time of formation, and can vary in color, texture, or appearance.
Glass tile is tested for abrasion per ASTM C1027. Glass tile is generally more abrasive resistant than ceramic tile, and some glass tile is suitable for heavy commercial use.
Thermal Shock Resistance:
Glass tile must pass shock cycling when tested per ANSI A137.2 Section 7.9. Glass tile is not suitable for applications with an instantaneous temperature change of more than 100°F.
Static Coefficient of Friction:
SCOF testing will conform to ASTM C1028. Floor applications with exposure to water, oil, grease, etc., can create slippery conditions, and caution should be taken in product selection.
Glass tile should not be installed on single-coat mortar bed walls framed with wood or metal, and should never be bonded directly to wood substrates. Substrates should be flat to avoid excessive mortar thickness.
Mortars should be specific for glass tile installation.
