An acoustic isolation mat for placement between a subfloor and a finished floor with a poured underlayment includes a bottom layer of entangled fibers contacting the subfloor; and a top layer attached to the bottom layer and being a water resistant nonwoven polymeric fabric over which the underlayment is poured.

Multi-functional underlayment acoustical mat and system

A method of installing a flooring system including pouring a gypsum underlayment on a substrate, allowing the underlayment to set, but not dry. A water-borne epoxy sealer is provided and applied to the wet, but set, underlayment.

Method of installing a flooring system utilizing gypsum underlayments

A method of applying a flooring system on a wood subfloor, including providing a sealer for direct application to the wood subfloor; applying the sealer to the wood subfloor; and allowing the sealer to dry and cure, forming a sealed and stable wood subfloor.

Method for sealing wood subfloors

The present invention relates to a sound rated floor system for inhibiting sound transmission between floors. The system includes a corrugated steel deck; a first layer of cementitious material or board or sheet applied over the corrugated steel deck; a sound insulation mat or board applied over the first layer; a second layer of cementitious material applied over the sound insulation mat or board. The floor system has an IIC rating of at least 25 and the corrugated steel deck provides at least 50 percent of the ultimate load carrying capacity under static and impact loading of the floor system with a floor deflection of at most 1/360 of the floor span.
