The highest performing, commercially graded, acoustic carpet tiles in the Acoufelt floor line feature QuietBack™. When a carpet offers QuietBack™, you know that its construction has been optimized for acoustic performance. This is accomplished by attaching the face pile layer directly to the felt, allowing the pile and backing to work together. The air flow capability of the tile increases significantly, which in turn raises acoustic absorption. Our acoustic carpet tiles have an acoustic performance four to five times that of standard carpet tiles on the market.
