Reduce TV Noise and Voices Through Stud Party Walls

Our Essential Stud Wall Soundproofing System is a simple and effective way to reduce everyday airborne noise such as TV sound and conversation through existing plastered stud walls. Using two layers of 5kg MLV and two layers of 15mm Acoustic Plasterboard bonded directly to the wall, it provides a high-mass upgrade with a slim overall build-up.

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

Everyday Airborne Noise Reduction for Timber Stud Walls

This Essential system is designed to improve the sound insulation of existing plastered stud walls, particularly where the main issue is airborne noise such as talking and TV noise transferring through a separating wall. It's a great choice if you want a straightforward, DIY-friendly upgrade without moving to a clip/channel independent wall system.

The build-up consists of:

  • 2 layers of 5kg MLV (Soundproofing Mat), joints staggered
  • 2 layers of 15mm Acoustic Plasterboard, joints staggered
  • High Strength Contact Adhesive
  • Everbuild AC95 Acoustic Sealant
  • PVC Jointing Tape

The finished build-up is approximately 40mm 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 5kg MLV add dense mass to help reduce airborne sound transmission, 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

This makes the system well suited to reducing talking and TV noise through stud party walls.

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
  • 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

  • Effective everyday noise reduction for stud party walls — dual 5kg MLV layers and dual acoustic plasterboard combine to add significant mass to an existing plastered stud wall, helping reduce TV noise, conversation, and general neighbour noise
  • Two layers of 5kg MLV for added mass — bonded directly to the existing wall with staggered joints, adding dense mass to help reduce airborne sound transmission through the wall structure
  • Two layers of 15mm Acoustic Plasterboard — applied over the MLV with staggered joints to further increase mass and improve overall sound reduction, 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 installation straightforward and 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 5kg MLV directly to the wall using contact adhesive
  3. Sealing joints as required and applying Jointing Tape
  4. Installing the second layer of 5kg 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.
