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

Cork is the perfect choice for environmentally friendly flooring underlayment for sound reduction and stress crack protection under hardwood, laminate, ceramic and stone floors. It can also be used for wall covering, bulletin boards, trivets, arts, crafts, and much more.
