Accessories for 3.2mm Custom Cut Rubber Underlayment

Description - Our 3.2mm custom cut rubber underlayment is a millimeter thicker than our 2mm roll, but offers a greater amount of sound reduction comparatively. Rubber underlayments are very popular with hard surfaces, due to the fact that rubber is more rigid, and provide the firmness necessary to resist compression from heavy objects and foot traffic. Our underlayment is also mold and mildew resistant due to the addition of a antimicrobial additive which inhibits the growth of both. Our flooring underlayment also doesn’t hold water, which allows for installation of the underlayment without a vapor barrier. But if the flooring will be installed in an area where water may be present, then a vapor barrier would be required. Also a vapor barrier may be needed per the manufacturer’s warranty. This sound proofing underlayment is also very popular with our Grid-Loc and Modular tiles due to the fact that it is very thin and helps to reduce the noise that can be made from them. So if you are looking for an underlayment that is affordable but at the same time gives you good sound absorption, then this is the product for you.
