A resilient bar is a cold-rolled steel acoustic channel used to improve soundproofing in walls and ceilings. It helps separate plasterboard or acoustic board from the main structure, reducing vibration transfer and improving the overall performance of an acoustic build-up.
This resilient bar is supplied in a 3 metre length and has a corrosion-resistant finish, making it suitable for standard drywall and plasterboard systems. It is commonly used in homes, flats, offices, studios and commercial spaces where better noise control is required.
A resilient bar is a thin metal channel that is fixed to timber studs, ceiling joists or suitable wall and ceiling framing. Plasterboard is then fixed to the bar instead of being fixed directly to the structure behind it.
This creates a small flexible gap between the structure and the plasterboard. That separation helps reduce the amount of vibration that can pass through the wall or ceiling.
A resilient bar is used in soundproofing systems for walls and ceilings. It is especially useful where you want to reduce noise passing between rooms, floors or neighbouring properties.
It is commonly used for party walls, ceilings, stud wall upgrades, bedrooms, home offices, media rooms, studios, flats, apartments and shared buildings.
Sound can travel through a building as vibration. When plasterboard is fixed directly to timber, metal or masonry, those vibrations can pass more easily through the structure.
A resilient bar helps by creating a flexible fixing point for the plasterboard. This creates a slight spring effect, helping to isolate the plasterboard lining from the structure behind it. When installed correctly, it can improve the sound reduction of the full wall or ceiling system.
Yes, a resilient bar can help reduce noise when it is installed as part of a complete soundproofing system. It is mainly used to help reduce airborne noise, such as voices, TV noise, music and general room-to-room sound transfer.
In ceiling systems, a resilient bar can also help reduce some vibration transfer from above. However, impact noise from footsteps usually needs a full acoustic system, including insulation, suitable board layers, acoustic sealant and sometimes additional isolation products.
A resilient bar can be installed on suitable wall and ceiling structures, including timber studs, timber joists and other compatible framing systems. It is commonly used in:
Fixing plasterboard directly to the structure creates a rigid connection. This can allow sound vibration to travel more easily through the wall or ceiling.
Using a resilient bar helps reduce this direct connection. The plasterboard is supported on the bar instead of being fixed straight back to the framing, which helps reduce vibration transfer and improves the performance of the soundproofing system.
A resilient bar works best as part of a complete soundproofing build-up. It is commonly used with:
Correct installation is very important. Plasterboard should be fixed to the resilient bar only. It should not be fixed through the bar and back into the timber or metal frame behind it.
If screws pass through into the structure, they can create a sound bridge. This gives vibration a direct path through the system and can reduce the acoustic benefit of the resilient bar.
A resilient bar is not normally used as a standalone soundproofing product. It performs best when used with the correct board layers, cavity insulation, acoustic membrane where required and acoustic sealant around the edges.

A resilient bar is a cold-rolled steel acoustic channel used in wall and ceiling soundproofing systems. It helps decouple plasterboard or acoustic board from the main structure, reducing direct vibration transfer and improving the acoustic performance of the complete build-up.

A resilient bar can be used in wall and ceiling systems where improved acoustic performance is required. It is commonly installed in:
A resilient bar is used to reduce the direct connection between the plasterboard layer and the wall or ceiling structure. This helps reduce vibration transfer and improves the soundproofing performance of the complete system.
It is mainly used to help reduce airborne noise, such as voices, TV noise, music and general room-to-room sound transfer. In ceiling systems, it can also help reduce some vibration transfer from above when used as part of a full acoustic build-up.
A resilient bar should be installed the correct way around and fixed only at the designed fixing flange. The plasterboard should then be fixed to the resilient bar, not through the bar and into the structure behind.
If screws pass through the plasterboard, through the resilient bar and into the timber or metal frame behind, this can create a sound bridge. A sound bridge gives vibration a direct route through the system and can reduce acoustic performance.
A resilient bar is not a complete soundproofing system on its own. It performs best as part of a full wall or ceiling build-up, normally including acoustic mineral wool, acoustic plasterboard, acoustic membrane where required, and acoustic sealant around all weak points.
The final soundproofing result will depend on the existing structure, bar spacing, board layers, installation quality and how well gaps and flanking paths are controlled.
Before installation, check the correct fixing type for the supporting structure. Fixings should securely hold the resilient bar in place without distorting the profile.

A resilient bar is used to help decouple plasterboard or acoustic board from the main wall or ceiling structure. When installed correctly, it creates a small flexible break between the board layer and the framing behind it, helping to reduce vibration transfer and improve the performance of the full soundproofing system.
Correct installation is very important. A resilient bar only works properly if the plasterboard is fixed to the bar and not through into the timber, metal or ceiling structure behind it. If the board is accidentally fixed back into the structure, it can create a sound bridge and reduce the acoustic benefit.
Check the wall or ceiling structure before installation. A resilient bar is commonly fixed to timber studs, ceiling joists, battens or suitable framing systems. The structure should be secure, dry and capable of supporting the finished board layers.
You should also check the board layout, number of plasterboard layers and fixing centres required for your system. Bar spacing can vary depending on the system design, board weight and installation area, so always follow the supplier or project specification where available.
Before fitting the resilient bars, make sure the installation area is ready. The surface or frame should be:
If acoustic mineral wool is being used inside the cavity, this is usually fitted before the plasterboard layers are installed.
Use a tape measure and level to mark where each resilient bar will be fitted. The bars should be straight, evenly spaced and installed in the correct direction for the wall or ceiling system.
For walls, a resilient bar is usually fitted horizontally across the studs or framing. For ceilings, a resilient bar is usually fitted across the joists. Always follow the system guidance for spacing and orientation.
If a bar needs to be shortened, measure carefully and cut it using tin snips or a suitable metal cutting tool.
Take care when handling cut metal edges, as they can be sharp. Wear gloves and avoid leaving sharp offcuts in the work area.
Position the resilient bar against the marked line and fix it through the correct fixing flange only. The bar should be securely fixed to the structure without being bent, crushed or distorted.
Do not over-tighten fixings in a way that deforms the bar. The shape of the bar is what helps create the spring effect, so it needs to remain correctly formed.
If the soundproofing system includes acoustic mineral wool, fit it into the cavity before boarding. The insulation should sit neatly between the studs or joists without being heavily compressed.
Acoustic mineral wool helps absorb sound inside the cavity, while the resilient bar helps reduce vibration transfer through the structure. Together, they improve the performance of the full wall or ceiling build-up.
Offer the plasterboard or acoustic board into position and fix it to the resilient bar only. This is the most important part of the installation.
If a screw goes through into the structure behind the resilient bar, it can create a direct sound bridge. This gives vibration a route through the system and can reduce the acoustic performance.
Leave a small gap around the perimeter of the board layer where it meets adjoining walls, ceilings or floors. This gap should then be sealed with acoustic sealant.
Do not hard-fill the perimeter with rigid filler before acoustic sealing, as this can create a rigid connection. Acoustic sealant helps maintain the separation and reduces sound leakage around the edges.
Seal any weak points in the system, including board edges, service penetrations, socket areas and gaps around pipes or cables.
For sockets and switches, use suitable acoustic detailing such as acoustic putty pads where required. Small gaps can reduce soundproofing performance, so careful sealing is important.
Once the boards are installed and sealed, the wall or ceiling can be finished according to the project requirements. This may include taping, jointing, plastering and decorating.
Avoid adding fixings that go through the finished board layer and into the original structure unless they are part of the approved system design. Unplanned rigid fixings can reduce the benefit of the resilient bar.
For wall soundproofing, a resilient bar is commonly fixed horizontally across timber studs or suitable framing. The plasterboard or acoustic board is then fixed to the bar rather than directly to the studs.
This method is often used for party walls, stud wall upgrades, bedrooms, home offices, media rooms, studios and shared walls where airborne noise is a problem.
For ceiling soundproofing, a resilient bar is commonly fixed across ceiling joists. The plasterboard or acoustic board is then fixed to the bars below.
This method is often used to help reduce noise from above, including voices, TV noise, general movement and some vibration transfer. For stronger impact noise reduction, it should be used as part of a complete ceiling soundproofing system.
A resilient bar is not a complete soundproofing system by itself. It is designed to improve the performance of a wall or ceiling build-up by reducing direct vibration transfer between the structure and the board layer.
For best results, use a resilient bar with suitable acoustic mineral wool, acoustic plasterboard, acoustic membrane where required and acoustic sealant. The final performance will depend on the existing structure, installation quality, board layers, bar spacing and how well flanking paths are controlled.
