Resilient Bar 3m
Resilient Bar 3m is designed to be used to isolate the plasterboard from direct contact with the above ceiling, it works to dissipate sound reducing the transmission across the ceiling of a room. The bars on their own will give an acoustic transmission by approximately 11db, when combined with a mineral wool insulation in the voids above you can see improvements of approximately 15-17db. We recommend using Rockwool RWA45 with a resilient bar system, you will see even further acoustic improvements, bettering the performance of the system. Resilient Bar is to be fixed to metal studs, fix bar at 600mm vertical centres. Fix the initial Resilient Bar 50mm down from the head of partition and the last bar 50mm from the floor. Screw fix the Resilient Bars to the studs using wafer headed self drilling screws. Screw fix the plasterboard to the Resilient Bar only, ensuring the screw does not touch the metal substrate. Bars are joined by butting together on the stud. Resilient bar is also suitable for fixing to a timber ceiling at 600mm centres. You may reduce the spacing of the resilient bars to ensure the load of plasterboard is more evenly distributed.
