The Independent Resilient Bar Stud Wall system works by creating a new timber stud frame in front of the existing wall. This separates the new acoustic wall build-up from the original structure, helping reduce direct sound and vibration transfer.
Rockwool RW3 75mm is fitted within the new frame to absorb sound within the cavity. Resilient bars are then fixed to the frame, creating a flexible mounting point for the acoustic board layers. The 19mm Acoustic Plank and 15mm dB Board add mass, while the optional Tecsound membrane can be used between layers for additional acoustic performance.
This system can be upgraded by including the Tecsound 50SY self-adhesive membrane between the board layers. This adds extra acoustic mass without significantly increasing the wall depth.
For rooms with multiple noise paths, performance can also be improved by treating adjacent floors, ceilings, sockets, gaps and flanking walls. The wall system will perform best when the whole room is considered, not just the main party wall.
This solution is suitable for party walls, separating walls, bedrooms, living rooms, home offices, studios and spaces where airborne noise is passing through an existing wall.
It is especially useful where a higher-performance wall system is needed and where there is enough space to build a new independent frame in front of the original wall.
Install a new timber stud frame in front of the existing wall, keeping it independent where possible. Fit Rockwool RW3 75mm neatly within the stud frame, avoiding gaps or compressed sections.
Fix resilient bars horizontally across the frame, then install the 19mm Acoustic Plank. If using the optional membrane, apply the Tecsound layer between the board layers. Finish with the 15mm dB Board, seal all perimeters with acoustic sealant and use resilient tape where required to reduce rigid contact points.
