Product Summary

If you poured hot coffee into a paper cup as compared to hot coffee into a foam cup, it's easy to see why the insulating value of Warm N Quiet Subfloor is superior to other types of subfloor products.

SUPERSEAL Warm N Quiet Subfloor is a dimpled sheet with an integrated foam layer that maximizes footfall noise reduction and enhances thermal insulation. The air gap created by the dimpled plastic membrane allows substrate moisture to evaporate keeping moisture away from the floor finish.

For laminate click flooring that is less than 12mm or for nail down hardwood, carpet or vinyl installations, a 5/8's inch or thicker tongue and groove plywood/OSB layer is required on top of the Warm N Quiet Subfloor.
