USG Durock Brand Uncoupling Mat - 355 sq. ft. Roll

USG Durock Brand Uncoupling Mat - 355 sq. ft. Roll

A waterproof underlayment membrane helps suppress the transfer of lateral movement in a subfloor to preserve the integrity of the tile installation.

Features

• Roll size: 43" x 98' (1.1m x 30m)
• Provides uncoupling, waterproofing, and vapor management of the substrate
• Lighter, thinner alternative to 1/4" tile underlayment panels
• A low-density core helps keep the membrane flat during installation
• Rot-proof and resistant to solvents and alkalis
• Ceramic tile installation can take place immediately after the membrane is installed

• This mat is an LDPE film with a spun bond polypropylene non-woven fabric on the top side and a needle-punched polypropylene fleece on the bottom side

Applications

• In interior and exterior* applications for both residential and commercial floors
• To renovate older floors to address existing in-plane cracks in the subfloor
• To diminish the transfer of stresses beneath the flooring associated with expansion and contraction between different substrate materials
