SoundSense Isolation System - Wall Isolation Bar



Simple - Simple System to install to installation costs are kept low.

Effective - This system offers an additional 5-6dB performance on traditional resilient bar. ca. 23dB improvement.

Fool-proof - System consists of 2 parts as opposed to a multi part system making installation even simpler.

Strong - The system offers superior load bearing capabilities as opposed to some other resilient bar systems.

Acoustic Performance

The SoundSense Isolation System helps to ensure compliance with Document E of the Building Regulations 2003.

By decoupling the internal lining system with SoundSense Isolation System the acoustic performance can be enhanced by more than 23dB on standard systems and 5 to 6 dB on some existing resilient systems.


SoundSense in an acoustic isolation system for ceilings and walls that completely de-couples the wall and ceiling linings and effectively delivers the "room within a room" concept often referred to by acoustic consultants.  It dramatically reduces both airborne and impact noise transfer between adjacent rooms typically producing an additional 5 to 6 dB improvement on some resilient bar systems.

The system has been designed to be flexible, simple and easy to install.  It is a 2 park system as opposed to some of the more complex multi-part systems often used where acoustic isolation/decoupling is required.

SoundSense is appropriate for all building types from residential properties to large commercial developments and is equally suited for both new build and refurbishment.  It is also suitable for fitting onto timber and metal stud walls, concrete soffits and timber joists on ceilings.

The damping clips ensure total isolation but also as they are fixed from both sides they ensure a much better load bearing capacity than most standard systems - up to 80kg's per m2.

Traditional resilient bar systems provide acoustic isolation for plasterboard walls and ceilings by use of a vibration absorbing steel channel which is fixed onto timber studs on and onto timber ceiling joists.  Typically these systems are fixed along one edge allowing the other free edge to flex and so by absorb sound/vibrations.  Resilient bars attempt to create an acoustic break between floor joist and the plasterboard ceiling or the timber wall studding and the plasterboard.

To operate correctly these resilient bars/channels need to be highly flexible, if they are too rigid they cannot effectively dampen sound/vibrations.  The requirement for flexibility has an obvious effect on their load bearing capabilities.  Also being fixed on one side they are not completely isolated from the studwork or joists.

Good resilient systems claim to deliver a 17dB improvement over standard dry lining solutions.

Resilient bar systems are often the only practical option when soundproofing a ceiling when constrained by height issues, as they typically only add an inch on to the original ceiling depth.

Note:-  This product must only be used in conjunction with the SoundSense Isolation Clip

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. Slide the required quantity of SoundSense Clips along the SoundSense bar. The bottom row of bar and clips should be no further than 100mm off the floor. The top row should be no further than 100mm below the ceiling.

5. The remaining SoundSense Bar and Clips should be spaced at no more than 600mm centres vertically. The Clips should be spaced a maximum of 600mm horizontally.

6. Where necessary ensure that the SoundSense Bar overlap by 200mm and that the overlaps don’t sit on a clip. Fix 4 self tapping screws into the shoulders of the channel where there is a join for a secure joint. The SoundSense Bar must not touch any adjoining surfaces.

7. Fix your first layer of acoustic plasterboard to the SoundSense 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 SoundSense 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 SoundSense 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 SoundSense Bar and Clips they should be installed no further than 100mm from the adjacent walls. The remaining clips should be spaced at a maximum of 600mm centres vertically and horizontally. You can now proceed from step 6 in the instructions above. The Channels should run perpendicular to the joists. Instead of using M20 soundproofing mat use 10kg Soundproofing Mat.
