Designed for existing timber stud walls
Uses the current wall structure
Improves mass, absorption and isolation
This system is designed to upgrade an existing stud wall without building a completely independent wall in front of it.
Resilient bars fixed to the stud frame
Helps reduce direct vibration transfer
Creates separation for the board layers
The resilient bar layer helps decouple the acoustic boards from the existing frame, reducing the amount of vibration passing through the wall.
Rockwool RW3 75mm within the cavity
19mm Acoustic Plank and 15mm dB Board
Optional Tecsound membrane upgrade
The layered system adds absorption, mass and separation to improve the acoustic performance of the existing stud wall.
Acoustic performance can vary depending on the existing stud wall construction, cavity depth, board condition, flanking paths and installation quality. For best results, avoid rigid bridging, fit insulation neatly and seal all perimeter gaps carefully.
The Stud Wall Upgrade Resilient Bar system improves an existing stud wall by adding absorption inside the cavity, a resilient fixing layer and dense acoustic board layers to the room side of the wall.
Rockwool RW3 75mm is fitted within the existing stud cavity to reduce resonance inside the wall. Resilient bars are then fixed across the studs, creating a flexible mounting point for the acoustic boards and helping reduce direct vibration transfer through the frame.
The 19mm Acoustic Plank and 15mm dB Board add mass to the wall. The optional Tecsound membrane can be installed between the board layers for extra acoustic density where higher performance is needed.
This system can be upgraded by including the Tecsound 50SY self-adhesive membrane between the 19mm Acoustic Plank and the 15mm dB Board. This adds extra mass without greatly increasing the overall wall depth.
For stronger performance, it is also worth reviewing common flanking paths such as floors, ceilings, sockets, adjacent walls and gaps around the perimeter. The wall system will only perform properly if sound is not simply bypassing it through another route.
This solution is suitable for existing stud walls where you want to improve airborne sound reduction without building a full independent frame in front of the wall.
It can be used in bedrooms, living rooms, home offices, studios and shared spaces where noise such as voices, TV, music or general neighbour noise is passing through a stud wall.
Start by checking the existing stud wall is suitable for upgrading. If the wall cavity is accessible, fit Rockwool RW3 75mm neatly between the studs, avoiding gaps and over-compression.
Fix resilient bars horizontally across the stud frame, then install the 19mm Acoustic Plank to the bars. 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. Take care not to screw through the resilient bars into the studs when fixing the board layers, as this can reduce the isolation benefit.
Our team are on hand to answer any questions and help you choose the right wall soundproofing system.
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 designed to improve an existing stud wall using Rockwool insulation, resilient bars and acoustic board layers.
It is useful when you want to upgrade the existing wall rather than build a separate independent wall in front of it.
This system is mainly designed to reduce airborne noise through stud walls, such as voices, TV noise, music and general room-to-room noise.
If the noise is travelling through floors, ceilings or structural junctions, those areas may also need to be considered.
This system upgrades the existing stud wall, whereas an independent stud wall system uses a new separate frame in front of the original wall.
The independent option usually takes up more space but can offer stronger separation from the original structure.
The Tecsound membrane is optional, but it can improve the system by adding extra acoustic mass between the board layers.
If you are dealing with stronger airborne noise or want the better-performing version of the system, it is worth including.
No. The acoustic board layers should be fixed to the resilient bars only, not through into the studs behind.
If screws bridge through into the stud frame, the isolation benefit of the resilient bars can be reduced.
It can be installed by competent DIY users, but it requires careful resilient bar fixing, board handling and acoustic sealing.
Small mistakes such as rigid bridging, missed gaps or poor perimeter sealing can reduce the performance of the system.
