Fiberock Brand Aqua-Tough Interior Panels from the United States Gypsum Co. (USG) are engineered to provide increased resistance to abuse. Because Aqua-Tough's formulation provides water resistance through the core, the panels are approved for use in wet areas.

Designed to be installed and finished like traditional wallboard, the new panels feature a smooth surface that can be either painted or finished with ceramic tile. Fiberock Brand Aqua-Tough Interior Panels are available in 1/2- and 5/8-inch thicknesses, with the 5/8-inch variety earning UL classification for fire resistance (Type X).
