Plus Stud Wall Soundproofing System

Best For

  • Timber stud party walls and separating walls where louder airborne noise is the primary concern — louder voices, TV at higher volume, or more noticeable general neighbour noise

Application

  • Wall soundproofing — existing plastered stud walls in residential properties where the Essential system is insufficient

System Depth

  • Approximately 45mm overall build-up from the existing wall face

Availability

  • Usually In Stock

Notes

  • Suitable for DIY installation; electrical sockets and switches must only be removed and reinstated by a qualified electrician

Higher Performance Sound Reduction for Stud Party Walls

Our Plus Stud Wall Soundproofing System is designed for reducing more noticeable airborne noise through existing plastered stud walls, where everyday solutions aren't quite enough. Using two layers of 10kg MLV and two layers of 15mm Acoustic Plasterboard bonded directly to the wall, it provides a higher-mass upgrade for improved sound reduction.

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 Airborne Noise Through Stud Walls

This Plus system is a step up from our Essential tier and is intended for situations where you're dealing with louder airborne noise through a timber stud separating wall — louder voices, TV at higher volume, or more noticeable general neighbour noise.

The build-up consists of:

  • First layer of 10kg MLV (Soundproofing Mat) bonded to the existing wall
  • Second layer of 10kg MLV, joints staggered
  • First layer of 15mm Acoustic Plasterboard, leaving a small perimeter gap
  • AC95 Acoustic Sealant at perimeter
  • Second layer of 15mm Acoustic Plasterboard, joints staggered
  • Final perimeter seal with AC95 Acoustic Sealant
  • PVC Jointing Tape at MLV joints
  • High Strength Contact Adhesive throughout

The finished build-up is approximately 45mm overall from the existing wall face.

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 sound insulation by adding high-mass soundproofing materials directly to the wall surface:

  • Two layers of 10kg MLV add significantly more mass than standard matting, helping reduce louder airborne noise, with staggered joints to minimise sound leakage at seams
  • Two layers of 15mm Acoustic Plasterboard further increase mass and improve overall sound reduction, with staggered joints and a finish-ready surface
  • 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
  • 15mm Acoustic Plasterboard — 2 layers
  • 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 airborne noise — dual 10kg MLV layers and dual acoustic plasterboard combine to deliver significantly more mass than single-layer direct-bonded systems
  • Two layers of 10kg MLV for dense mass — bonded directly to the existing wall with staggered joints, adding substantial mass to help reduce louder airborne noise including voices, TV at higher volume, and general neighbour noise
  • Two layers of 15mm Acoustic Plasterboard — applied over the MLV with staggered joints to further increase mass and rigidity, improving overall sound reduction and providing a finish-ready surface
  • Direct-bonded system — no frame or fixings required — the system is bonded directly to the existing plastered stud wall using contact adhesive, keeping the build-up slim relative to the performance level
  • Suitable for existing plastered stud walls — designed to be applied to an existing sound, plastered stud wall surface without structural alteration
  • DIY-friendly installation — no specialist tools or frame construction required; suitable for competent DIYers comfortable with plasterboard work
  • 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 to be fixed to an existing plastered stud wall
  • It is intended primarily for airborne sound reduction
  • 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
  • Electrical sockets and switches should only be removed and reinstated by a qualified electrician


Installation Summary 

Installation involves:

  1. Preparing the wall so it is clean, dry, sound, and free from defects
  2. Bonding the first layer of 10kg MLV directly to the wall using contact adhesive
  3. Sealing joints as required and applying Jointing Tape
  4. Installing the second layer of 10kg MLV, staggering joints where possible
  5. Installing the first layer of 15mm Acoustic Plasterboard (maintaining a small perimeter gap)
  6. Sealing perimeter gaps with AC95 Acoustic Sealant
  7. Installing the second layer of 15mm Acoustic Plasterboard, staggering joints where possible
  8. Applying a final perimeter seal before finishing
  9. The completed wall can then be skimmed or tape and jointed ready for decoration.
