Description
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.
