Reduce Everyday Airborne Noise and Footfall Through Timber Floors

Our Essential Timber Floor Soundproofing System – Bonded LVT 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 SilentCork3 Acoustic Underlay and Mapei Ultrabond Eco VS90 Plus adhesive, this system is designed specifically for bonded LVT installations.

To make things easier, our online calculator works out the quantities required for your project, with an additional 5% already allowed for waste.

A Slim Timber Floor Upgrade Designed for Bonded LVT

This Essential system is designed for timber floor constructions where you want a straightforward improvement in both airborne noise reduction (voices, general household noise) and impact noise reduction (footfall and general vibration through the floor). This system is intended for use where the final floor finish will be bonded LVT, using the correct underlay and adhesive for the floor covering.

The build-up consists of:

  • 2 layers of 5kg MLV (Soundproofing Mat), joints staggered
  • SilentCork3 Acoustic Underlay
  • Mapei Ultrabond Eco VS90 Plus Adhesive
  • Everbuild AC95 Acoustic Sealant
  • PVC Jointing Tape
  • High Strength Contact Adhesive

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:

  • Two layers of 5kg MLV add dense mass to help reduce airborne sound transmission, with staggered joints to minimise sound leakage at seams
  • SilentCork3 Acoustic Underlay reduces impact noise and improves acoustic comfort under bonded LVT, and provides a suitable bonding surface compatible with the Mapei VS90 adhesive system
  • Mapei Ultrabond Eco VS90 Plus Adhesive is used to bond the LVT correctly to the SilentCork3 layer as per manufacturer guidance
  • AC95 Acoustic Sealant seals perimeter gaps and weak points to maintain airtightness
  • Jointing Tape seals MLV joints to prevent sound leakage at seams

What We Supply

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

  • 5kg MLV (Soundproofing Mat) — 2 layers
  • SilentCork3 Acoustic Underlay
  • Mapei Ultrabond Eco VS90 Plus Adhesive
  • High Strength Contact Adhesive
  • AC95 Acoustic Sealant
  • PVC Jointing Tape

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

Key Benefits

  • Practical entry-level upgrade for everyday noise and footfall — two layers of 5kg MLV combined with SilentCork3 underlay provide a meaningful improvement in both airborne and impact noise without structural work
  • Dual 5kg MLV layers for added mass — two rolls of 5kg mass loaded vinyl with staggered joints add dense mass to help reduce everyday airborne noise including talking, TV, and general household noise
  • SilentCork3 Acoustic Underlay for impact isolation — installed above the MLV layers to reduce footfall and impact noise, and to provide a suitable bonding surface for the LVT finish, compatible with the Mapei VS90 adhesive system
  • Suitable for bonded LVT installations — the SilentCork3 and Mapei Ultrabond Eco VS90 Plus combination provides a bonded LVT-ready substrate as part of the complete system
  • DIY-friendly installation — no structural work required; the system is laid over the existing floorboards and the LVT is bonded directly to the SilentCork3 layer
  • Slim build-up depth — approximately 10mm overall, making it one of the slimmest options in the range and suitable for most rooms without door or threshold issues
  • Built-in 5% waste allowance — calculator quantities include a 5% overage to reduce the risk of under-ordering on site


Important Notes 

  • This system is designed for timber floors intended to be finished with bonded LVT 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 adhesive and flooring manufacturer’s guidance for installation and curing times


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 SilenceCork 3 underlay Using Mapei VS90 as required for a correct bonded LVT installation
