5/30/2023 0 Comments Whisper mat sound control membrane![]() ![]() emissions Whisper Mat CS membrane cannot be used (see "Limitations"). If subfloor moisture/ vapor is beyond 4lb. Subfloor must be checked for excessive moisture. Concrete subfloors must be dry, clean and free of dirt, grease, wax, paint, oil or anything that would adversely affect adhesion of the WhisperMat. Flooring and membrane must acclimate to job site conditions before installation. Installation and subfloor requirements must also conform to TCA standards. WhisperMat-CS Brochure 8/12/06 7:31 AM Application Standards: Apply Primer Cut to Correct Length INSTALLATION: Follow flooring manufacturer’s recommended installation instructions. APPLICATIONS The sound absorption properties combined with the anti-fracture properties makes Whisper Mat CS an excellent system to enhance ceramic and stone flooring installation performance in: The aggressive rubberized adhesive retains its flexibility throughout the floor’s life span and will not dry out or decay with time. Whisper Mat CS contains no V.O.C’s and is environmentally safe which allows it to be used in confined areas. The Polyester mesh fabric top makes an excellent bonding surface for latex modified thin set and medium bed mortars. The membrane is tacky on the bottom providing superior adhesion to concrete, steel and wood substrates. Compositions and Materials: Whisper Mat CS is constructed of a top layer of Reinforced Polyester Mesh Fabric embedded into rubberized adhesive, a middle layer of dense cross-linked poly-olefin foam sheeting for additional sound reduction properties with a bottom layer of aggressive rubberized adhesive with an attached release liner for peel & stick application. Use latex modified thin-set mortar to install tile over Whisper Mat CS. Installations requiring more than 3/8" of thin-set mortar need to be raised with a self-leveling compound or a pre-mortar bed and allowed to cure prior to installation of Whisper Mat CS. Whisper Mat CS is designed for thin-set applications. ![]() Installation procedures and job site conditions must be in accordance with flooring manufacturer’s recommendations and TCA installation standards. For expansion joints, reference TCA Method EJ171. Whisper Mat CS is not recommended to cover joints or cracks larger than 3/8." For installation over plywood substrates and for expansion JOINTS, refer to TCA Handbook F147-99. Whisper Mat CS is not recommended for use where horizontal floor movement is greater than 1/4." Existing cracks larger that 3/16" should be prepared with proper backing material prior to installation of membrane. (tested by "Calcium Chloride Test” method) or where constant water vapor transmission is present. Limitations: Whisper Mat CS is not recommended for use on concrete floors when hydrostatic head pressure or excessive water vapor transmission exceeds 4lbs. WhisperMat is approved over radiant heated floors. It may be applied to any structurally sound and clean surface including: concrete, plywood, gypsum underlayments, precast floor panels, OSB, Ceramic tile, terrazzo, natural stone, leveling and patching compounds, cement backer board, existing VAT, VCT and vinyl floors. Basic Uses: Whisper Mat CS is designed to be an underlayment for ceramic and stone tiles where transmitted or impact sound reduction is required.
