USG Fiberock Aqua-Tough Tile Backerboard is a unique, fiber-reinforced gypsum product that represents a new era in substrate performance for wet or dry areas, as recognized within the TCNA Handbook and International Residential Code. This durable panel offers superior performance and tile bond in addition to an integral water-resistant core.
