Abstract

A flooring assembly ( 10 ) comprising at least one vertically lapped fibrous material layer ( 14 ), at least one pressure sensitive adhesive layer ( 12 a ) including a flexible substrate ( 12 b ), a mesh ( 12 c ) and an adhesive ( 12 d ) located along the flexible substrate, and at least one moisture impermeable membrane layer ( 16 ).

First claim

1 . A flooring assembly comprising:
a) at least one thermoformable short fiber nonwoven material layer; b) at least one pressure sensitive adhesive layer including a flexible substrate, a mesh and an adhesive located along the flexible substrate; and c) at least one moisture impermeable membrane layer.

2 . The flooring assembly of claim 1 , including a concrete layer located beneath all other layers.

3 . The flooring assembly of claim 1 , including a composite layer located above all other layers.

4 . (canceled)

5 . The flooring assembly of claim 1 , including a first pressure sensitive adhesive layer located in direct planar contact with a first surface of the at least one thermoformable short fiber nonwoven material layer.

6 . The flooring assembly of claim 5 , including a second pressure sensitive adhesive layer located in direct planar contact with a second surface of the at least one moisture impermeable membrane layer.

7 . The flooring assembly of claim 1 , wherein the thermoformable short fiber nonwoven material layer is vertically lapped fibrous material layer.

8 . (canceled)

9 . The flooring assembly of claim 1 , wherein the at least one moisture impermeable membrane layer is located in direct planar contact with the at least one thermoformable short fiber nonwoven material layer.

10 . The flooring assembly of claim 1 , wherein the assembly comprises:
a. exactly one thermoformable short fiber material layer; b. exactly one moisture impermeable membrane layer located in direct planar contact with a second surface of the thermoformable short fiber nonwoven material layer; c. a first pressure sensitive adhesive layer located in direct planar contact with a first surface of the thermoformable short fiber nonwoven material layer; and d. a second pressure sensitive adhesive layer located in direct planar contact with a second surface of the moisture impermeable membrane layer.

11 . (canceled)

12 . (canceled)

13 . The flooring assembly of claim 1 , wherein the density of the thermoformable short fiber nonwoven material layer is at least about 100 g/m 2 and less than about 800 g/m 2 .

14 . The flooring assembly of claim 1 , wherein the thermoformable short fiber nonwoven material layer comprises a polyethylene terephthalate material.

15 . The flooring assembly of claim 1 , wherein the pressure sensitive adhesive layer comprises a UV cured adhesive.

16 . The flooring assembly of claim 1 , wherein the at least one pressure sensitive adhesive layer includes a release liner.

17 . The flooring assembly of claim 1 , wherein the assembly, is substantially free of any liquid adhesive.

18 . The flooring assembly of claim 6 , wherein the moisture impermeable membrane layer comprises a low density polyethylene material.

19 . (canceled)

20 . The flooring assembly of claim 1 , wherein the at least one pressure sensitive adhesive layer adheres to any adjacent layer without use of any solvent.

21 . The flooring assembly of claim 1 , wherein the at least one pressure sensitive adhesive layer has a high loss factor such that the overall loss factor of the assembly is higher than that of the at least one thermoformable short fiber nonwoven material layer by itself.

22 . (canceled)

23 . The flooring assembly of claim 1 , wherein the assembly is substantially free of any foam material.

24 - 28 . (canceled)

29 . The flooring assembly of claim 1 , wherein the flooring assembly is applied in between a concrete slab and a wood floor.

30 .- 44 . (canceled)

45 . The flooring assembly of claim 1 , wherein fibers of the thermoformable short fiber nonwoven material layer include thermoplastic fibers.

46 . The flooring assembly of claim 1 , wherein the moisture impermeable membrane layer comprises a polyamide, a polyolefin, a polycarbonate, a polyester, an epoxy based material, a thermoplastic polyurethane, or any combination thereof.

47 .- 48 . (canceled)
