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.
