DESCRIPTION USG Fiberock® Brand Tile Backerboard and Underlayment panels are manufactured from an environmentally sustainable, specially engineered combination of synthetic gypsum and cellulose fibers. USG Fiberock Tile Backerboard and Underlayment panels have an integral water-resistant composition that offers durability, superior performance and exceptional tile bond. USG Fiberock Tile Backerboard and Underlayment panels are engineered to meet water-, mold- and indentationresistance needs under and/or behind tile, resilient flooring, carpeting, hardwood flooring and laminate flooring in new construction and/or remodeling. USG Fiberock Tile Backerboard is also an ideal substrate for painted wall surfaces, when transitioning from tile to paint.

They may be used in fire rated wall assemblies as listed in the UL Fire Resistance Directory under “Type FRX-G".

It also offers greater resistance to indentation than other underlayment products and can be used throughout a home—in both wet and dry areas— regardless of the flooring material chosen.
