Natural Cork Underlayment Roll

Mon, 28 Nov 2005 02:40:20 +0100

Underlayment

Natural CORK, the natural choice for sound control underlayment.
Cork contains millions of air-filled pockets per cubic inch. These air pockets compress under pressure, regaining their shape once pressure is removed thereby creating a gentle cushiony surface flooring material. With cork you are literally walking on air! This same characteristic is responsible for cork's success as an acoustic insulation.

100% Cork Composition Roll can be used for:
			Underlayment
			Sound reduction insulation
			Stress crack suppression
			Scratch protection for furnishings, floor and wall
			Bulletin boards
			Art projects
			Trivets
			Wall coverings

Quietwalk Underlayment

Fri, 28 Dec 2007 23:06:57 +0100

Our recycled cotton floor underlayment smoothes out little sub floor imperfections while quieting impact sound and floor to ceiling noise. Although it is promoted as an upgrade underlayment taking the place of poly foam, it doesn't carry a heavy upgrade price when compared to cork or rubber. Some advantages include:

1/8" thick
Over 80% post-industrial recycled fibers
Superior sound absorption due to unique manufacturing process
Added R-Value of .5 helps keep floor warm in the winter and cool in the summer
Advanced moisture wicking and evaporation technology
Safe anti-microbial component resists mold and bacteria
High density supports overlaying floor
Flexibility hides minor sub-floor imperfections
Cost effective

Installation Instructions

1. Be sure the sub floor surface is clean and dry
2. Roll underlayment over the sub floor with the vapor barrier film (blue side) facing up.
3. The perimeter edges of underlayment need to be 1/2 to 3/4 inches away from the wall.
4. Seams need to be butted together flush, do not overlap the pad. Tape the seams with water and tear resistant, utility-grade, poly-coated cloth backed tape that has a very aggressive adhesive (duct tape).
5. Install flooring according to the manufacturer’s installation instructions.
