Higher Performance Floor Soundproofing for Floating / Loose Lay Finishes

Our Plus Timber Floor Soundproofing System – Loose Lay LVT & Laminate is designed for timber floors where you’re dealing with more noticeable noise and want a higher performance upgrade. Using two layers of 10kg MLV combined with 5mm Terrac underlay, this system helps reduce both airborne noise and impact noise from footfall, while remaining practical to install under floating floor finishes.

To make things easier, our online calculator does all the hard work for you by working out the quantities required for your project, with an additional 5% already allowed for waste, helping ensure you have everything needed to complete the installation.

Designed for Louder Noise Through Timber Floors (Loose Lay / Floating Finish) 

Our Plus Timber Floor Soundproofing System – Loose Lay LVT & Laminate is a step up from our Essential tier and is intended for situations where you’re dealing with louder airborne noise and/or more noticeable impact noise through a timber floor. This system is intended for use where the final floor finish will be loose lay LVT or a laminate/floating floor type installation.

The build-up consists of:

The finished build-up is approximately 15mm overall.

Important Supply Information 

All components required for this system are supplied by us as part of the calculator output. You do not need to source additional system materials separately.

How the System Works 

This system improves floor sound insulation by combining high mass and impact isolation:

  • The two layers of 10kg MLV add significantly more mass than standard matting, helping reduce louder airborne noise
  • 5mm Terrac underlay helps reduce impact noise and improves acoustic comfort under floating floor finishes
  • AC95 Acoustic Sealant helps close perimeter gaps and weak points
  • Jointing Tape helps seal joints and improve airtightness

Best Suited For 

  • Timber floors with loose lay LVT or laminate/floating floor finishes
  • Residential properties where noise transfer is more noticeable
  • Improving comfort where you want a higher level of reduction for: Louder voices / general household noise TV noise at higher volume Footfall / impact noise
