Lightweight, trowel-applied flooring underlayment for absorbing sound.
Dex-O-Tex Acousti-Fill is a lightweight, trowel-applied flooring underlayment designed to absorb sound and reduce sound transmission. Its latex composition contains a sound absorptive, vibration-damping aggregate, which markedly reduces Impact Noise Radiation (INR) and improves the Sound Transmission Classification (STC).
Acousti-Fill can be installed beneath a variety of floor finishes, including carpet, resilient tile, ceramic tile. It can also be used to absorb sound on promenade decking for apartment or condo complexes or in mechanical equipment rooms to dampen intense sound vibrations.
