Resilient Bar is a thin metal channel designed to substantially improve the sound insulation of plasterboard walls and ceilings. The channel effectively isolates the plasterboard from the studwork, eliminating 'direct contact' to dissipate sound which would normally be transferred through the frame. This system is easy to install and produces excellent results especially when used with suspended high mass ceilings. Our resilient bars, or resilient channels as they are sometimes called, are superior quality and highly flexible unlike other types that are on the market which are just too rigid to have a beneficial effect.

Resilient Bars typically add between 3-6dB to the acoustic performance of an otherwise identical structure.
Even greater improvements in soundproofing can be gained by:- Adding an additional layer of plasterboard to one or both sides Adding a layer of Soundproofing Mat in-between the layers of plasterboard Securing the battens via our 50mm x 5mm neoprene strips and securing the bars to the battens with our 50mm x 5mm neoprene strips

TECHNICAL
Bar Cutting:	Resilient Bar can easily be cut with tinsnips or hacksaw.
Bar Installation:	If fitted directly to the underside of an existing ceiling, 50mm battens should be screwed to the ceiling at approx. 600mm centres (depending on if you are using acoustic quilt or acoustic mineral wool), right angled to the joists. Care must be taken to ensure that the fixings used are secured to the joists and NOT just to the plasterboard. On walls the bars should be mounted at right angles to the frame max. 600mm centres, with the narrow mounting flange at the bottom and the wider flange at the top. This allows the plasterboard to draw itself away from the studwork.
Plasterboard:	A double layer of 12.5mm (or thicker) plasterboard, or similar composite, should be used and fitted to within 5mm of the surrounding walls/ceiling. Joints should be staggered in all direction. ALL joints should be secured to the resilient strip with the appropriate length screws at 230mm centres.
Fixing:	Secure the first, or thickest layer, of plasterboard to the resilient bars with the appropriate length drywall screws. IT IS ESSENTIAL THAT THE SCREWS ONLY PENETRATE THE CORRUGATED WEBS AND DO NOT COME INTO CONTACT WITH THE RESILIENT BAR SUPPORTS OR BATTENS. Screw the second layer of plasterboard using the correct length LONGER screws taking care to overlap the joints of the first layer making sure that the screws ONLY penetrate the corrugated web part of the resilient bar.
Edge Sealant:	Flexible Mastic Sealant should be applied to ALL the edge perimeters after the installation of EACH layer to achieve optimum results.
Finishing:	All plasterbaord joints should be finished with traditional jointing methods and plaster skimmed before decorating.
Dimensions:	Steel Guage : 0.5mm Weight          : approx. 0.37Kg/m Length          : 3 metres
Performance:	When installed beneath an existing ceiling with 50mm acoustic mineral wool and 30mm of plasterboard applied, improvements in both airborne noise and impact sound would normally be well in excess of 9-10dB. Fire resistance with a minimum of 30mm of plasterboard applied would be 1 hour.
