soundproofing: Resilient Bar (Rbar)
overview
A vibration absorbing thin steel channel used on timber studs for walls and ceilings. This allows the new wall or ceiling to be de-coupled from the vibrating surface which will reduce both vibration and impact noise penetration.
testimonial
"What a clever product! We used this on our walls to help reduce the vibration sound of bass from next doors sound system. It has seriously helped reduce it and our walls no longer vibrate."

Use on Ceilings
Resilient Bars are essential to help bring suspended timber floors into compliance with the building regulations for noise control through converted separating floors for flats.
Used in connection with other sound insulating materials we supply, the bars will create an effective acoustic break between the bottom of the existing joists and the ceiling. If not fitted directly beneath the floor joists, Sound Reducing Resilient Bars can be supported by 50mm square battens screwed to the underside of any existing ceiling. (See installation instructions above).
The inclusion of the Bars alone will make around an 11dB improvement. Combined with our AMW 100 between the joists and a double layer of 12.5mm Acoustic Plasterboard we would expect this to be around a 16dB improvement. This should make a considerable difference to reducing the noise nuisance thay you may be experiencing.
Plasterboard is then screwed to the corrugated section of the bar using our self drilling screws and for best results; two layers totalling 30mm thickness should be installed. Alternatively, our Acoustic Plasterboard can be used.
A greater sound insulation improvement can be gained if a min of our Acoustic Mineral Wool (AMW50) is installed between the battens before fixing the plasterboard.
When installed beneath an existing ceiling with AMW50 and 30mm of plasterboard applied, improvements in both airborne noise and impact sound would normally be well in excess of 300% this can be further enhanced if our Acoustic Membrane is sandwiched between the plasterboard layers.
Use on Walls
Resilient Bars are also recommended to upgrade walls; particularly effective at reducing loud music or bass sound passing though the wall.
Ideally you would build a new stud batten frame spaced away from the current wall. This will create a sealed air gap between the new wall and the existing one. Fill in between the studs with our Acoustic Mineral Wool. This is friction fitted but should not be installed too tightly.
You would then screw our R Bars onto this frame horizontally using our self drilling screws followed by a layer of 12.5 mm Acoustic Plasterboard. We would then advise using a layer of our SBM5 Soundproofing Mat bonded to the first layer of plasterboard with our spray adhesive. To finish the application, add a final layer of plasterboard. You need to make sure that both layers of plasterboard do not touch the surround walls or floor. Fill in the small gap with flexible non-hardening sealant and then your whole system will be floating on the bars. For detailed installation instructions please see our Installation Guide above.
