Floor Underlay Rolls
Acoustic underlay lays a continuous decoupling layer between the structural subfloor and the finished floor, breaking the direct vibration path that carries footfall and impact between rooms. We stock two supplier families — Serenity and Dura — spec'd for high-IIC residential and multi-family floor assemblies.
