Reduce noise travelling through plasterboard ceilings and walls with Hush Bar Resilient Bar. Its flexible metal profile separates the plasterboard lining from the supporting structure, helping reduce airborne sound and impact vibration.
Use Hush Bar beneath timber joists or battens, or on timber and metal stud walls, for new builds and acoustic refurbishments.
10 bars per pack · 2.4m x 65mm x 16mm per bar · 24 linear metres per pack
A resilient connection for your plasterboard
Rather than fixing plasterboard directly to the structure, Hush Bar creates a resilient fixing surface. This helps limit the transfer of voices, TV noise and footstep vibration through separating floors and walls, while adding just 16mm before the plasterboard lining.
Fixing centres and installation
- For ceilings, screw-fix Hush Bars beneath timber joists or battens at 600mm bar centres, running at right angles to the joists.
- For timber or metal stud walls, fit the bars at 450mm centres.
- Fix the plasterboard to the bars, keeping its screws clear of the supporting joists or studs to preserve the resilient connection.
Hush lists a suspended load of up to 30kg/m² for the standard 16mm bar. Check the combined lining weight against this limit and follow the specified Hush fixing arrangement.
Acoustic performance
Hush System 2003 Plus incorporating Hush Bar achieved 55 dB L’nT,w impact, 55 dB DnT,w airborne and 49 dB DnT,w + Ctr. These are results for that tested floor and ceiling arrangement.
How many do I need?
Plan your ceiling rows at 600mm centres, work out the 2.4m lengths required along each row, then divide the total number of bars by 10 and round up to whole packs.
For example, a 4.8m x 3m ceiling allowing six rows at no more than 600mm centres needs two bars per 4.8m row. That is 6 × 2 = 12 bars, so order 2 packs of 10. Check joints, end supports and cuts against your final layout.
You’ll also need
Choose the board layers and fixing lengths for your lining detail. Plasterboard screws must secure the lining to the bar without reaching the joists or studs behind.
Add each extra you need, then adjust its quantity in your basket.
