JCW Silent Board

This super slim and easy to fit acoustic wall panel upgrades existing walls to drastically reduces sound transmission and save space. A simple and very effective direct to wall acoustic overlay board with just half the thickness of most other products on the market, it’s perfect for soundproofing party walls.

JCW Silent Board is specially designed for upgrading existing walls so that sound transmission from neighbours or adjoining rooms is reduced. Because it is so slim and effective, at just 27.5mm, there is little compromise on living space.

It is manufactured by laminating a 15mm acoustic resilient layer to a 12.5mm layer of acoustic grade plasterboard.

It can be applied to either masonry or stud walls and is also suitable to reduce flanking noise up and down walls.

It is also an ideal solution where existing walls have failed a pre-completion test.

    DIY Installation Guide

    • Step 1. Remove skirting boards and any coving as appropriate
    • Step 2. Start the installation from the bottom left or bottom right corner of the wall
    • Step 3. Offer the first board to the wall ensuring it is fitted square and allow a 5mm gap around the perimeter edge of the wall
    • Step 4. The board is fixed using 9 drywall screws and plugs evenly placed in 3 rows x 3 screws. Ensure there is a solid fix to the existing wall (each board weighs 24.7kgs)
    • Step 5. Once the first board is in position, the next board in the bottom row can be butted up to the first board – continue this process until all boards are in place in the bottom row – and trimmed as necessary to allow the 5mm perimeter gap
    • Step 6. Boards may be cut with a suitable handsaw and sharp trimming knife
    • Step 7. Start the second row from the end of the first row with staggered joints and continue in this fashion until the fitting is complete
    • Step 8. Fill the 5mm perimeter gap with JCW Acoustic Sealant
    • Step 9. The acoustic wall is now ready for a plaster skim or your choice of other final decorative finish
