A complete family of water- and mold-resistant wall and underlayment products offering outstanding performance characteristics and easy installation is available from United States Gypsum Company.

FIBEROCK Brand AQUA-TOUGH Interior Panels are engineered to provide increased resistance to abuse while outperforming paper-faced or glass-mat-faced panels in residential and commercial applications.

Their unique AQUA-TOUGH formulation provides water resistance through the core, and the panels are approved for use in wet areas, including tub surrounds. Designed to be installed and finished like traditional wallboard, the panels feature a smooth surface that can either be painted or finished with ceramic tile. They are ideal for use in high-traffic areas where resistance to abuse, moisture, mold and fire are especially important qualities.

The panels are available in 1/2"- and 5/8-inch thicknesses, with the 5/8-inch-thick panels earning UL classification for fire resistance (Type X).

FIBEROCK Brand Underlayment - AQUA-TOUGH is a moisture-resistant residential flooring underlayment that delivers superior performance, enhanced versatility and quick, hassle-free installation.

The panels offer an environmentally friendly alternative to conventional wood-based underlayment products. They can be used in both wet and dry areas of the home and are ideal for application under vinyl, ceramic tile, hardwood flooring, laminate flooring and carpeting.

The underlayment is available in 4- by 4-foot sizes with 1/4"- and 3/8-inch thicknesses, and in a 4- by 8-foot size with a 3/8-inch thickness. It is protected by a 15-year warranty.

All FIBEROCK products are designed to be cut using a utility knife and straight edge, but handsaws or low-rpm power saws can also be used. They are made from 95 percent recycled materials and have earned the "Green Cross" certificate from Scientific Certification Systems, making them an environmentally friendly product option in sustainable building construction.
