ReWall QuarterBack Floor Underlayment

ReWall QuarterBack is a high-performance flooring underlayment. It has the sound control of cork, the compressive and flexural strength of cement board, and the workability of engineered wood. Like all ReWall products, the QuarterBack is inherently moisture and mold resistant, without added chemicals, adhesives or biocides. These unique properties make ReWall QuarterBack an ideal underlayment solution for all kinds of flooring products, including laminate floors, hardwood, ceramic tile and carpets.
