Soundproofing Floors in Flats (Impact & Airborne Noise Reduction – UK)

Why Does Noise Travel Through Floors?

• Impact noise: Caused by footsteps, moving furniture, or dropped objects—travels directly through floorboards and joists.
• Airborne noise: Voices, TV, or music can pass through gaps, cavities, or poorly insulated floors.
• Most UK flats and houses have timber or suspended floors, which easily transmit both types of noise unless properly treated.
• Key reason: Lack of mass, underlay, or isolation lets noise pass through and around floors.

Basic Step-by-Step: How to Soundproof a Floor in a Flat

1. Choose the Right System for Your Floor Type:
   • Laminate/hard floors vs. carpeted floors require different solutions.
2. Install Acoustic Underlay:
   • Use a dense, specialist underlay designed to absorb impact noise.
3. Add a Mass Loaded Vinyl (MLV) Layer:
   • Place a 5kg Soundproofing Mat or MLV under the underlay for airborne noise reduction.
4. Use Perimeter Isolation Strips:
   • Install isolation strips around the edge of the floor to prevent flanking noise through skirting boards and walls.
5. Seal All Gaps and Edges:
   • Use acoustic sealant around the perimeter, and ensure there are no gaps for sound to leak through.
6. Finish with Your Chosen Flooring:
   • Lay laminate, carpet, or other flooring as normal on top of the treated base.

Installation Tips & Common Mistakes

• Always use perimeter isolation strips to stop sound leaking into walls.
• Don’t skip the MLV layer—this is key for airborne noise.
• Make sure all layers are laid flat and joints are tight.
• Seal all edges, especially around pipes, radiators, and doorways.
