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.

"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."

description.
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.
