Products / Atlas WeatherMaster Tile Underlayment

WeatherMaster Tile is Atlas's stackable, high-temperature self-adhering underlayment of modified asphalt under a woven polyester surface that bonds with tile foam adhesives and resists slippage under stacked tile, and can also be used under metal. The data sheet gives a 36 in. x 65 ft. roll (195 sq. ft.), a 50 mil minimum thickness, high-temperature stability to 260 degrees F, a 180-day UV exposure and a pass on the Miami-Dade County TAS 103 test, with an ASTM E108 fire rating based on the roof covering.
