Specification

Description Fiberock
®
panels are manufactured from an environmentally sustainable, specially engineered combination of
synthetic gypsum and cellulose fibers.
Fiberock has an integral water-
resistant composition that offers durability, superior performance and exceptional tile bond.
Fiberock panels are
engineered to meet water-, mold- and indentation-resistance needs under and/or behind tile, resilient flooring,
carpeting, hardwood flooring and laminate flooring in new construction and/or remodeling.
Fiberock tile
backerboard is also an ideal substrate for painted wall surfaces, when transitioning from tile to paint.
Fiberock underlayment provides a smooth, flat surface that resists swelling and warping often seen with wood-
based underlayments, and contains none of the resins, adhesives or solvents that can stain floor covering
materials. 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.
