## Abstract

A sound-deadening product for a flooring system with a subfloor may be installed by a single installer. The sound-deadening product has a sound-deadening upper portion with a bottom surface and a subfloor contacting layer affixed to the bottom surface of the sound-deadening upper portion. The subfloor contacting layer may include a film or be a laminate. The laminate may include a nonwoven sheet and a film. The nonwoven sheet is generally co-extensive with the sound-deadening upper portion. The nonwoven sheet is adhered to the bottom surface of the sound-deadening upper portion. The film is generally co-extensive with the nonwoven sheet. The film is a polymer film with a thickness ≤3 mils. An upper surface of the film is adhered to a bottom surface of the nonwoven sheet, and a bottom surface of the film is in contact with the subflooring. A method for single installer installation of the sound-deadening product is also disclosed.

## Claims

### Claim 1

A method for single installer installation of a sound-deadening product in a flooring system on a subfloor, the subfloor is a wood product, comprising the steps of:
providing the sound-deadening product, the sound-deadening product has a sound-deadening upper portion with a bottom surface and a subfloor contacting layer affixed to the bottom surface of the sound-deadening upper portion, the subfloor contacting layer is a laminate, the laminate includes a nonwoven sheet and a film, the nonwoven sheet is generally co-extensive with the sound-deadening upper portion, a top surface of the nonwoven sheet is adhered to the bottom surface of the sound-deadening upper portion, the film is generally co-extensive with the nonwoven sheet, the film is a polymer film with a thickness less than or equal to 3 mils, the film is in contact with the subfloor;
sliding the sound-deadening product into place on the subfloor with the single installer; and
finishing a floor over the sound-deadening product.

### Claim 2 (depends on 1)

The method of claim 1 wherein the wood product includes: plywood, particle board, or flake board.

### Claim 3 (depends on 1)

The method of claim 1 wherein the flooring system is a cementitious or gypsum flooring system.

### Claim 4 (depends on 1)

The method of claim 1 wherein the polymer film is a polyolefin film.

### Claim 5 (depends on 4)

The method of claim 4 wherein the polyolefin film is a polyethylene film, or a polypropylene film or a film of polyethylene and polypropylene.

### Claim 6 (depends on 1)

The method of claim 1 wherein the film is a solid film, or the film has no perforations, or the film is not a nonwoven, or the film is an extruded sheet, or the film is not a membrane.

### Claim 7

A sound-deadening product in a flooring system on a subfloor for single installer installation, the subfloor is made of a wood product, comprising:
the sound-deadening product has a sound-deadening upper portion with a bottom surface and a subfloor contacting layer affixed to the bottom surface of the sound-deadening upper portion, the subfloor contacting layer is a laminate, the laminate includes a nonwoven sheet and a film, the nonwoven sheet is generally co-extensive with the sound-deadening upper portion, the nonwoven sheet is adhered to the bottom surface of the sound-deadening upper portion, the film is generally co-extensive with the nonwoven sheet, the film is a polymer film with a thickness less than 3 mils, an upper surface of the film is adhered to a bottom surface of the nonwoven sheet, and a bottom surface of the film is in contact with the subflooring.
