Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An acoustic isolation flooring system consisting of: a sound reduction mat of: a first layer made of two separate material layers made of different materials that are bonded to each other, wherein one of said material layers is a water-resistant and wear-resistant fabric and another of said material layers is a water-resistant, sound dampening material; and a single, second layer of a water resistant, nonwoven polymeric fabric including a plurality of tangled fibers and space between said fibers that defines an air layer for decreasing sound transmission through said second layer; said first layer of water and wear-resistant fabric is bonded to said second layer of nonwoven polymeric fabric, and an underlayment of a finished floor is poured over said first layer of said water and wear-resistant fabric. 2. The system of claim 1 , wherein said water and wear-resistant fabric is laminated to said nonwoven polymeric fabric, and said latter fabric is pinbonded MB fabric. 3. The system of claim 1 wherein said water and wear-resistant fabric is SM-250 polypropylene and said nonwoven polymeric fabric is a pinbonded MB fabric.
