Claims3
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.
