Resilient Bar | 3m | 60 × 14mm
Resilient Bar is a single-part corrugated steel channel fixed to timber joists or stud frames to create a decoupled surface for acoustic plasterboard. The bar’s corrugated profile acts as a spring between the structural substrate and the plasterboard, absorbing vibration and preventing direct contact between the two surfaces. This decoupling reduces the transmission of both airborne and impact noise through the wall or ceiling assembly.
Resilient Bar is the entry-level decoupling solution in the range — a single-part system that is straightforward to install and cost-effective for standard domestic applications. For higher-performance requirements, the MuteClip clip and channel system provides greater isolation. Each bar is 3m long. Minimum order: 10 bars.
Applications
-
Acoustic ceilings — timber joisted floors — fix bars perpendicular to the joists at maximum 600mm centres, starting no further than 100mm from the adjacent walls. Fix acoustic plasterboard to the corrugated section of the bar using self-drilling screws. Fill the joist cavity with Rockwool to approximately 80% depth before fixing the bars. Suitable for bringing suspended timber floors into compliance with Part E Building Regulations.
-
Acoustic stud walls — fix bars vertically to the stud frame at maximum 600mm centres, with the bottom row no further than 100mm from the floor and the top row no further than 100mm from the ceiling. The bar must not touch any adjoining surfaces. Fix acoustic plasterboard to the bar, leaving a 5mm perimeter gap on all sides.
-
Flat conversions and separating floors — used as part of a ceiling assembly to reduce impact and airborne noise transmission from the floor above. Combine with Rockwool insulation, MLV, and acoustic plasterboard for improved performance.
Product Benefits
-
Single-part system — straightforward installation. Resilient Bar is a one-component decoupling solution. Fix to the substrate, attach plasterboard to the corrugated face — no clips or secondary channel required.
-
Corrugated steel profile — vibration absorption. The corrugated section of the bar acts as a spring, absorbing vibration at the fixing point and preventing it from transmitting directly into the plasterboard surface.
-
Compatible with acoustic plasterboard and MLV. Performance is improved by combining the bar with acoustic plasterboard and a layer of MLV between plasterboard layers. A minimum of two layers of acoustic plasterboard is recommended for optimal results.
-
Part E suitable. When used as part of a correctly specified assembly with appropriate insulation and plasterboard, the resilient bar system can contribute to compliance with Part E Building Regulations for separating walls and floors.
-
3m length — 10 bar minimum order. Due to delivery requirements, a minimum order of 10 bars applies.
Installation
Walls: Install a timber stud frame with a minimum 5mm gap from the existing wall. Apply resilient sealing tape to the frame perimeter where it contacts the floor, ceiling, and adjoining walls. Fill the stud cavity with Rockwool to approximately 80% depth. Fix Resilient Bar vertically to the studs at maximum 600mm centres — bottom row no further than 100mm from the floor, top row no further than 100mm from the ceiling. The bar must not touch any adjoining surfaces. Where bars overlap, ensure a minimum 200mm overlap. Fix the first layer of acoustic plasterboard to the bar using self-drilling screws — screws must not contact the studwork. Leave a 5mm perimeter gap and seal with AC95 Acoustic Sealant. Adhere MLV to the plasterboard using contact adhesive, then fix the second layer of acoustic plasterboard in a staggered brick bond pattern. Seal all perimeter gaps with AC95.
Ceilings: Fill the joist cavity with Rockwool to approximately 80% depth. Fix Resilient Bar perpendicular to the joists at maximum 600mm centres, starting no further than 100mm from the adjacent walls. Proceed as per wall installation from step 6, substituting 10kg MLV for the wall specification.

1. Begin by installing a wood stud frame with a minimum gap of 5mm from the existing brick wall. Adhere Resilient Sealing tape to the frame perimeter. Fix the timber to the floor, ceiling and adjoining walls with the resilient tape sandwiched between the timber and the adjoining surface. This will help to reduce flanking sound transmission.
2. The timber frame studs should be fitted at a maximum of 600mm centres with noggins.
3. Insert Rockwool between the stud frame, held in snugly between the studs. The cavity should be filled approximately 80% of the depth to avoid the Rockwool from being compressed.
4. The bottom row of Resilient bar should be no further than 100mm off the floor. The top row should be no further than 100mm below the ceiling. The Resilient Bar must not touch any adjoining surfaces.
5. The remaining Resilient Bar should be spaced at no more than 600mm centres vertically. There should be fixings a maximum of 600mm centres.
6. Where necessary ensure that the Resilient Bars overlap by 200mm.
7. Fix your first layer of acoustic plasterboard to the Resilient Bar. Leave a 5mm gap around the perimeter of the wall. The acoustic plasterboard should not be in contact with any adjoining surfaces. Ensure that the length of screws fixing the plasterboard to the Resilient Bar don’t contact the studwork.
8. Seal the gap around the perimeter of the wall with AC95 Acoustic Sealant.
9. Next adhere M20 Soundproofing Mat to the plasterboard in a brick bond fashion using Advanced Acoustics Contact Adhesive.
10. Fix the final layer of acoustic plasterboard, staggering the joints from the previous layer of acoustic plasterboard. Ensure you use screws that are long enough to fix to the Resilient Bar but are not so long that they touch the timber stud. Leave a 5mm gap around the perimeter of the wall.
11. Seal the perimeter and any other gaps with AC95 Acoustic Sealant.
12. The wall is now ready to be dry lined or plaster skimmed.
For a ceiling installation begin by installing Rockwool between the joists, this should be fitted snugly so that friction holds it in place. If required you can use thin wire to keep it suspended. The cavity should be filled approximately 80%.
When fixing the Resilient Bar it should be installed no further than 100mm from the adjacent walls. The bars should be spaced at a maximum of 600mm centres vertically and horizontally. You can now proceed from step 6 in the instructions above. The bar should run perpendicular to the joists. Instead of using M20 soundproofing mat use 10kg Soundproofing Mat.
