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

Installation Summary

Installation involves:

1. Preparing the wall so it is clean, dry, sound, and free from defects
2. Bonding the M20 Soundproofing Mat directly to the wall using contact adhesive
3. Sealing perimeter gaps and any joints with AC95 Acoustic Sealant
4. Applying Jointing Tape across the mat joints
5. Installing the first layer of 15mm Acoustic Plasterboard
6. Sealing gaps again
7. Installing the second layer of 15mm Acoustic Plasterboard, with staggered 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.
