Rubber underlayment offers some of the best sound absorption rates of any underlay. Rolled rubber underlayment can be installed under most flooring types and can be installed anywhere in your home or business. Rubber underlay is very easy to install and can be loose laid, taped, glued, nailed or stapled. This acoustical underlayment is a favorite under hardwoods and ceramics and helps to suppress crack formation in your floor. Rubber underlayment should not be used under luxury vinyl tiles, luxury vinyl planks, VCT or linoleum. Staining can occur if put under these flooring types. A vapor barrier is typically necessary in areas where moisture may be an issue.
