SEAL BEACH, CA -- Custom® Building Products has improved its WonderBoard® cementitious backerboard line with the launch of WonderBoard Lite. The new fiberglass mesh-reinforced cement backerboard for residential and commercial tile, stone, slate and thick-brick applications is up to 20% lighter than its predecessor while maintaining high-flexural strength and moisture resistance. WonderBoard Lite meets the performance standards of ANSI A118.9.WonderBoard® backerboard lighter

"Custom's WonderBoard is an established brand that stands for durability and ease of use for do-it-yourselfers and professionals who depend on the product on a daily basis," said Prashant Panchal, Senior Product Manager for Custom Building Products. "Preparing walls, floors, ceilings and counters is now less demanding with the new WonderBoard Lite. It offers the ideal combination of a lighter weight backboard with the durability and performance standards of traditional WonderBoard."

Developed for interior and exterior substrate applications, WonderBoard Lite backerboards feature an advanced cementitous formula reinforced to offer durable performance. The new formula also offers outstanding stability and moisture protection for wet area installations to reduce the damaging effects of moisture. It contains no wood fiber or gypsum.

Custom now offers WonderBoard Lite in a 7/16-inch thickness designed to align to 1/2-inch drywall without the use of shims or spacers on wall studs. Preprinted patterns on the panel surface make it easy to score, snap, cut and fasten during installation.

WonderBoard Lite panel sizes include 36 x 60 x 7/16 inch for floors, walls and countertops, and 36 x 60 x 1/4 inch for floors and countertops.
