	Floating Wood and Laminate Flooring Underlayment Quiet Walk: Our laminate floor underlayment smoothes out little subfloor imperfections while quieting impact sound and floor to ceiling noise. Not only does it dampen ambient sound in the room it's installed in, but it also inhibits sound from traveling into the room below. 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. Insulating Underlayment Insulayment The insulating value of Insulayment helps keep floors warm in the winter, and cool in the summer.
