Floor soundproofing depends mainly on timber or concrete construction, impact or airborne noise, and the floor finish you want to install. Choose the build-up around those three points rather than buying underlay by thickness alone.
What Problem Are You Solving?
Footsteps & Impact
Use resilient acoustic layers to reduce vibration from footsteps, dropped objects and furniture movement.
Voices & Airborne Noise
Airborne transfer often needs more than a soft underlay. Timber floors may also benefit from cavity insulation and additional mass.
Both
Many flats and conversions need a combined build-up that treats vibration, cavity resonance, mass and perimeter isolation together.
Timber vs Concrete Floors
Timber floors: if the joist void is accessible, acoustic mineral wool can help control resonance. The deck above can then be upgraded with a resilient mat, acoustic overlay board or floating treatment, depending on the required performance and finish.
Concrete floors: the slab already provides useful mass, so the surface treatment is often aimed mainly at impact vibration. Acoustic underlays, resilient layers and floating floor systems are common routes.
Your Final Floor Finish Matters
Carpet, laminate, engineered timber, vinyl and tile do not all use the same acoustic build-up. Check product compatibility before ordering, particularly where a system is intended to float or where hard finishes could create rigid bridges.

Before You Order
- Confirm whether the floor is timber or concrete.
- Identify whether the main problem is impact, airborne noise or both.
- Know the final floor finish and available build-up height.
- Measure the full area and allow for perimeter detailing and joints.
