Ideal for showers, bath surrounds, backsplashes, countertops, fireplaces, and floors or walls in wet or dry areas, PermaBase Plus offers a durable backerboard material that weighs 25% less than the company's standard cement board.

Acknowledging the efficiency benefits of a lighter weight material for installer, National Gypsum's cement board product manager Tony Fuller says the company "incorporated the attributes of PermaBase, but created a significantly lighter product that scores and snaps as easy as drywall, with a cleaner cut that still provides the performance you expect from PermaBase."

Manufactured in accordance with ASTM C 1325 and ANSI 118.9 standards, the maker says PermaBase Plus received the highest possible rating for mold and mildew resistance, achieving a panel score of 10 on the ASTM D 3273 test. PermaBase also features EdgeTech technology, with a tapered, reinforced edge design that allows for screws to be applied closer to the edge of the panels.

PermaBase Plus is approved for interior applications and select exterior applications, including outdoor kitchens, grills, and decks. It carries a 30 year limited warranty for interior applications and a 15-year limited warranty for exterior applications. National Gypsum | 800.628.4662 |
