Sound Control Flooring Systems: UL-Listed Assembly Guide

UL-listed in 110+ fire-rated floor-ceiling assemblies. Monofilament mesh and rigid platform technologies deliver consistent IIC and STC performance. Correct system specified for your building type, not substituted with the closest available option.

Sound Mat Durability: Moisture-Resistant and Load-Tested

Mats that compress under construction loads or absorb moisture lose their acoustic rating before the building opens. Impervious, rigid-under-load mats third-party tested to hold IIC and STC performance for the life of the building.

Gypsum Concrete Depth and IIC/STC Performance Data

Gypsum Concrete Depth and IIC/STC Performance Data

Every inch of gypsum depth changes acoustic output. Cure time: 24 hrs to walk, 28 days to full compressive strength. Do not apply finish flooring until moisture content is at or below 75% RH. Paired with Treadstone Elite, meets virtually any IIC/STC target in a single scope.
