Patent ID: 8528286

Claim:
A floor assembly, comprising: a sub-flooring layer; a top-flooring layer overlying the sub-flooring layer; and a sound control mat positioned between the sub-flooring layer and the top-flooring layer, the sound control mat comprising: a resilient layer of extruded polymer monofilaments, the polymer monofilaments being heat welded at junctions to form a matrix of tangled monofilaments, the resilient layer having a machine direction and a cross-direction, the resilient layer comprising a plurality of waves forming a repeating pattern of peaks and valleys, the waves extending in the machine direction and the cross-direction, each wave having a pair of legs, each leg extending from the peak of the wave to an adjacent valley, the average ratio of the width of the waves, as measured in the cross-direction, to the length of the waves, as measured in the machine direction, being at least about 2:1; and a fiberglass scrim bonded to the resilient layer at the valleys of the waves, the scrim comprising a plurality of fiberglass strands, the fiberglass strands comprising two sets of strands, the strands in one set of strands intersecting the strands in the other set of strands at angles of about 90°, the fiberglass scrim further comprising a water or moisture impermeable polymer coating extending between the two sets of strands; the resilient layer contacting the sub-flooring layer at the peak of the waves, the scrim contacting the top-flooring layer, wherein the peaks of the waves are configured to at least partially compress upon application of an impacting force to the top-flooring layer and recover their pre-compressed shape upon release of the impacting force.
