Separate timber stud wall
Acoustic mineral wool in the cavity
Reduced direct contact with the existing wall
This system is designed around a new independent frame, helping reduce vibration transfer from the original wall structure.
Resilient bars fitted to the stud frame
Helps isolate the board layers
Improves separation within the wall build-up
The resilient bars help decouple the plasterboard layers from the frame, reducing the amount of vibration passing through the system.
19mm Acoustic Plank
Optional Tecsound membrane
15mm dB Board finishing layer
This layered build-up adds mass, absorption and separation, making it suitable for stronger wall soundproofing requirements.
Acoustic performance can vary depending on the existing wall, frame depth, flanking paths, workmanship and whether the new frame is kept independent from the original structure. For best results, avoid rigid bridging and seal all perimeter gaps carefully.
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.

Contact usSound can travel through floor structures, especially in flats, bedrooms and rooms above or below occupied spaces. Floor soundproofing can help reduce impact noise, footsteps and airborne sound transfer.
If noise is travelling from above or below, the ceiling may also need treatment. Ceiling systems can help reduce airborne sound, vibration and impact noise through the floor-ceiling structure.
It is a wall soundproofing system built on a new timber stud frame in front of the existing wall.
The resilient bars help separate the acoustic board layers from the frame, reducing the amount of vibration that can pass through the wall build-up.
Yes, in many cases an independent frame system can perform better than a direct-to-wall system because it creates more separation from the existing structure.
It does take up more space, but it gives the system more opportunity to absorb, isolate and reduce sound transfer.
This system is mainly designed to reduce airborne noise through walls, such as voices, TV noise, music and general neighbour noise.
If the main issue is impact noise or vibration travelling through the building structure, floors and ceilings may also need to be considered.
The Tecsound membrane is optional, but it can improve the acoustic build-up by adding extra mass between the board layers.
If you are dealing with stronger airborne noise or want the best version of the system, it is worth including.
The final depth depends on the stud frame size, cavity depth, resilient bar and board layers used.
It will take up more room than a slim direct-to-wall system, but that extra depth is part of what helps improve performance.
It can be installed by competent DIY users, but it requires careful setting out, frame construction, resilient bar installation, board handling and acoustic sealing.
If the frame is bridged back to the existing wall or gaps are left around the perimeter, performance can be reduced.
