Protecto Wrap Whisper Mat CS Sound Control Flooring Underlayment For Tile 36" x 40' Roll (Model 109SPCS)

Whisper Mat CS is a peel & stick sheet membrane that reduces impact and airborne sound transmissions, and isolates “finished” flooring from subfloor cracks. Designed for thin-set tile applications where sound reduction is required, specified or desired.

Constructed of a top layer of reinforced polyester mesh fabric with a middle layer of sound reduction material and a bottom layer of aggressive rubberized adhesive with an attached release liner for peel & stick application, Whisper Mat CS also has the flexibility and strength to withstand structural movement and concrete shrinkage cracks up to 3/8" without transferring stress load to finished tile. Additionally, excellent moisture resistant properties make this the most comprehensive underlayment product for thin-set tile applications available.
