In the illustrated embodiment, the waves have irregularities as a result of the fact that the resilient layer is made from a plurality of extruded polymer monofilaments that are entangled, and some of the waves may have edges and/or dimensions that are slightly different than other waves in the resilient layer. The waves, in their illustrated embodiment, are shown in FIGS. The waves, as viewed from a side edge of the mat, may have a sinuous configuration or a serpentine configuration. The expression, “a plurality of waves forming a repeating pattern of peaks and valleys” is used herein to refer to the shape of the resilient layer of the inventive sound control mat. ![]() The term “cross-direction” refers to the direction that is oriented 90° from the machine direction. ![]() ![]() The term “machine direction” refers to the direction of the flow of polymer from an extruder when forming the inventive sound control mat. All combinations specified in the claims may be combined in any manner. It is to be understood that unless specifically stated otherwise, references to “a,” “an,” and/or “the” may include one or more than one, and that reference to an item in the singular may also include the item in the plural. DETAILED DESCRIPTIONĪll numerical ranges disclosed in the specification and claims may be combined in any manner. 1-4 wherein the sound control mat is shown in the form of a roll. 5 is a schematic illustration of the sound control mat illustrated in FIGS. 1-3 and 5 positioned between the sub-flooring layer and the top flooring layer, the resilient layer of the sound control mat contacting the sub-flooring layer, and the scrim of the sound control mat contacting the top-flooring layer.įIG. 4 is a side elevational view of a flooring system within the scope of the invention, the flooring system comprising a sub-flooring layer, a top flooring layer overlying the sub-flooring layer, and the sound control mat illustrated in FIGS. 2, this side view showing the resilient layer with a repeating pattern of peaks and valleys extending in the machine direction.įIG. 3 is a side elevation of the sound control mat illustrated in FIG. 1 with the mat turned over and rotated 90°, the scrim being shown in greater detail.įIG. 2 is a schematic illustration of the sound control mat illustrated in FIG. ![]() 1 is a schematic illustration of a sound control mat within the scope of the invention, the sound control mat comprising a resilient layer and a fiberglass scrim, part of the resilient layer being cut away to show the scrim.įIG. A number of the drawings are schematic illustrations which may not necessarily be drawn to scale.įIG. In the annexed drawings like parts and features have like references. This invention also relates to a floor assembly, comprising: a sub-flooring layer a top-flooring layer overlying the sub-flooring layer and the above-indicated sound control mat positioned between the sub-flooring layer and the top-flooring layer, the resilient layer contacting the sub-flooring layer, the scrim contacting the top-flooring layer. This invention relates to a 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, a cross-direction, a first side and a second side, 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, 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 overlying the second side of the resilient layer, the scrim comprising a plurality of fiberglass strands, the resilient layer being heat welded to the fiberglass scrim. Three-dimensional products are used with floor systems for reducing impact noise. The sound control mats are useful for noise control with flooring systems. This invention relates to sound control mats.
