Resilient Bars are a vibration absorbing thin steel channel used to decouple Acoustic Plasterboard from stud walls and timber joists of ceilings. This will significantly improve the soundproofing of any wall or ceiling when used along with other sound insulating products.
Resilient Bars are used to upgrade the soundproofing of party walls and ceilings. Particularly effective at reducing loud music or bass sound passing though any structure.
For walls, Ideally you would build a new stud frame spaced about 25mm away from the wall to be soundproofed. This will create a sealed air gap between the new wall and the existing one. Fill in between the studs with Acoustic Mineral Wool and it does not matter if the wool comes into contact with the existing wall. This is loose fitted and should not be installed too tightly. Screw the Resilient Bars onto the frame horizontally using self drilling screws followed by a layer of 15mm Acoustic Plasterboard.
We would then advise using a layer of SBM5 Soundproofing Mat bonded to the first layer of plasterboard with our Sta-Stuk special spray adhesive. To finish the application, add a final layer of acoustic plasterboard. You need to make sure that both layers of plasterboard do not touch the surrounding walls, floor or ceiling. Fill in the small gap with our flexible non-hardening acoustic sealant and then your whole system will be independent and floating on the bars. For detailed installation instructions please see the Installation Guide above from the link on the right hand side.
Resilient Bars are essential to help bring suspended timber floors into compliance with the Part E building regulations requirements for noise control through converted separating floors for flats.
Used in connection with other sound insulating materials, the resilient bars will create an effective acoustic break between ceilings and the joists above. If not fitted directly beneath the floor joists, Noise Reducing Resilient Bars can be supported by 50mm square battens screwed to the underside of any existing ceiling. (See installation instructions from link above right hand side).
A greater sound insulation can be gained if a minimum 50mm of Acoustic Mineral Wool (AMW50) is installed between the battens before fixing the acoustic plasterboard.
When installed beneath an existing ceiling with AMW50 and 30mm of plasterboard applied, expected improvements in both airborne noise and impact sound would normally be well in excess of 300% and can be further enhanced if SoundBlocker Membrane is sandwiched between the acoustic plasterboard layers.
The fitting of the Bars alone along with a double layer of 15mm acoustic plasterboard will usually achieve at least an 11dB improvement. Combined with our AMW 100 between the joists and a double layer of 15mm Acoustic Plasterboard we would expect this to be around a 16dB improvement. This should make a considerable difference to reducing the noise nuisance that may be experienced.
Acoustic plasterboard is screwed to the corrugated section of the bar using self-drilling screws and for best results; two layers totalling a minimum of 30mm thickness should be installed.
