Plus Timber Floor Soundproofing System – Carpet

Best For

  • Timber floors with a carpet finish where a higher level of sound reduction is needed for louder airborne noise or more noticeable footfall

Application

  • Timber floor soundproofing — residential properties where noise transfer is more noticeable and the Essential system is insufficient

System Depth

  • Approximately 21mm overall build-up above the existing floor (excluding carpet)

Availability

  • Usually In Stock

Notes

  • No structural work required — suitable for DIY installation over existing floorboards; check door and threshold clearances before ordering

Higher Performance Floor Soundproofing for Carpeted Timber Floors

Our Plus Timber Floor Soundproofing System – Carpet 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 Silent Floor Ultra Acoustic Underlay, this system helps reduce both airborne noise and impact noise from footfall, while remaining practical to install.

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

Designed for Louder Noise Through Timber Floors (Carpet Finish)

This Plus system 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.

The build-up consists of:

  • 2 layers of 10kg MLV (Soundproofing Mat), joints staggered
  • Silent Floor Ultra Acoustic Underlay
  • Everbuild AC95 Acoustic Sealant
  • PVC Jointing Tape
  • High Strength Contact Adhesive

The finished build-up is approximately 21mm overall, excluding the carpet finish.

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:

  • Two layers of 10kg MLV add significantly more mass than standard matting, helping reduce louder airborne noise including voices, TV at higher volume, and general household noise
  • Silent Floor Ultra Acoustic Underlay reduces impact noise from footfall and improves overall acoustic comfort under carpet
  • 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:

  • 10kg MLV (Soundproofing Mat) — 2 layers
  • Silent Floor Ultra Acoustic Underlay
  • 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

  • Higher performance than the Essential system for louder noise — two layers of 10kg MLV combined with Silent Floor Ultra Underlay deliver significantly more mass and impact isolation than single-mat systems
  • Dual 10kg MLV layers for dense mass — two rolls of 10kg mass loaded vinyl with staggered joints add substantial mass to help reduce louder airborne noise, including voices, TV at higher volume, and general household noise
  • Silent Floor Ultra Acoustic Underlay for impact isolation — installed above the MLV layers to reduce footfall and impact noise, and to provide a high-performance acoustic substrate directly under the carpet
  • Suitable for carpet finishes — Silent Floor Ultra provides a compatible acoustic base for carpet installations without requiring adhesive bonding to the floor finish
  • DIY-friendly installation — no structural work required; the system is laid over the existing floorboards and finished with carpet as normal
  • Practical build-up depth — approximately 21mm overall, making it suitable for most rooms; check door and threshold clearances before ordering
  • 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 carpet
  • 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


Installation Summary 

Installation involves:

  1. Preparing the floor surface so it is clean, dry, and free from debris
  2. Installing the first layer of 10kg MLV
  3. Installing the second layer of 10kg 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 Silent Floor Ultra Underlay ready for carpet fitting
