Reduce Everyday Airborne Noise and Footfall Through Timber Floors

Our Essential Timber Floor Soundproofing System – Loose Lay LVT or Laminate is a slim, practical solution for improving sound insulation through timber floors, helping reduce everyday airborne noise (talking/TV) as well as impact noise from footfall. Using two layers of 5kg MLV combined with 3mm Terrac underlay, this system is designed for loose lay LVT and laminate-style 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.

A Slim Timber Floor Upgrade for Floating / Loose Lay Finishes 

Our Essential Timber Floor Soundproofing System – Loose Lay LVT or Laminate is designed for timber floor constructions where you want a straightforward improvement in both:

  • Airborne noise reduction (voices, general household noise)
  • Impact noise reduction (footfall and general vibration through the 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 10mm 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 mass and impact isolation:

  • The two layers of 5kg MLV add dense mass to help reduce airborne sound transmission
  • 3mm 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

What We Supply 

The system calculator works out the estimated quantities required for the soundproofing materials we supply, including:

  • Rolls of 5kg MLV (Soundproofing Mat)
  • 3mm Terrac underlay
  • Contact Adhesive
  • AC95 Acoustic Sealant
  • Jointing Tape

We also include an additional 5% allowance for waste in the calculated quantities.

Important Notes 

  • This system is designed for timber floors intended to be finished with loose lay LVT or laminate/floating floor products
  • It is intended to improve both airborne noise and impact noise, but results will vary depending on the existing floor construction
  • Sealant quantities are an approximation only and should be treated as a guide
  • The calculator is provided as a guide only, and final quantities should always be checked before ordering
  • Always follow the flooring manufacturer’s guidance for underlay requirements and expansion gaps


Installation Summary 

Installation involves:

  1. Preparing the floor surface so it is clean, dry, and free from debris
  2. Installing the first layer of 5kg MLV
  3. Installing the second layer of 5kg MLV, staggering joints where possible
  4. Sealing joints as required and applying Jointing Tape
  5. Sealing perimeter gaps with AC95 Acoustic Sealant where required
  6. Installing 3mm Terrac underlay ready for the final loose lay / floating floor finish
