Product Description:

Acousti-Mat® LP is a unique blend of polymeric fibers of various shapes and sizes.  The blend of these fibers is a proprietary mix designed to provide excellent reductions in sound transmission and sound reflection.  The mat is bound together through a blend of polymer adhesives, which provide a tough durable mat with water repellant features.

Acousti‑Mat LP can be attached to a concrete subfloor, then topped with a Maxxon Underlayment.  The Acousti‑Mat LP is permanently encased in the underlayment, so when the floor goods are changed, the sound control system remains intact. With this application, the Acousti-Mat LP system can meet the 50 IIC sound control rating required by the International Building Code, before any floor goods are installed. Acousti-Mat LP achieves a Delta IIC of 19, that's approximately a 75% reduction in impact noise on concrete floor systems.
