A quality rubber acoustic underlay, correctly installed, should last the lifetime of the building — 25 years or more.

Why Rubber Lasts So Long

High-density recycled rubber — the material in our 6mm acoustic underlay — maintains its resilience under load. Unlike open-cell foam, it does not flatten, absorb moisture, or degrade over time.

What Reduces Lifespan

• Water ingress — always address damp before installing
• Incorrect installation — gaps or sound bridges
• Incompatible adhesives used directly on the underlay

When to Replace

If replacing floor finish, inspect the existing underlay. If it looks intact and undamaged, it will still perform. Our 12mm acoustic system is designed for longevity in high-use applications.
