Floor AssemblySerenity Underlay

Step 01

Underlay Rolls

Serenity acoustic underlay is a recycled rubber-composite mat that lays a continuous decoupling layer between the subfloor and the finished floor — breaking the direct vibration path that carries footfall and impact between rooms. We stock three thicknesses: the low-profile 6 mm, the balanced 9 mm, and the top-tier 12 mm.
