MuteClip XP Acoustic Isolation Resilient Bar System

MuteClip XP Acoustic Isolation Clip | 130 × 76 × 45mm

The MuteClip XP is a resilient isolation clip used to build a decoupled ceiling or wall frame. It mounts directly to the existing joist or structural substrate and accepts MuteClip Channel, which clips into the body of the clip to create a continuous, decoupled frame onto which plasterboard is fixed. Because the channel and plasterboard are isolated from the structure by the clip’s dual-density silicone pad, vibration from the structure above cannot travel directly into the ceiling below — reducing both impact and airborne sound transmission.

The XP variant accommodates ceiling drops of up to 65mm, making it suitable for installations where joists are uneven and a level ceiling plane needs to be established. Sold individually. MuteClip Channel must be ordered separately and is required to complete the system.

Applications

• Acoustic dropped ceilings — concrete and timber — fix clips to the underside of joists at the specified centres, click MuteClip Channel into the clips, and fix plasterboard to the channel. The decoupled frame prevents direct structural contact between the plasterboard and the substrate, reducing the transmission of impact noise from above (footfall, washing machines) and airborne noise (music, speech).
• Uneven joist correction — the XP clip’s 65mm drop range allows the channel to be set to a consistent level across joists of varying depth or alignment, eliminating the need for packing or additional framing.
• Wall decoupling — the clip and channel system can also be used on walls to create a decoupled frame for acoustic plasterboard, reducing airborne sound transmission through party walls and separating walls.
• Part E compliance — the MuteClip XP system is compliant with Part E Building Regulations (England, Wales, Northern Ireland, and Republic of Ireland). Tested performance: 35dB impact sound reduction, 60dB airborne sound reduction.

Product Benefits

• Dual-density silicone isolation pad. The silicone pad surrounds the fixing point and buffers the metal clip from the substrate, preventing vibration from bridging directly through the fixing into the frame. This is the critical element of the decoupling system — without isolation at the fixing point, structural contact is maintained and performance is significantly reduced.
• 35dB impact / 60dB airborne sound reduction. Independently tested performance figures for the complete MuteClip XP system with MuteClip Channel and acoustic plasterboard.
• Up to 65mm ceiling drop. Accommodates significant variation in joist depth and alignment, making it practical for retrofit installations in older buildings where joists are not level.
• Part E compliant. Suitable for use in separating floor/ceiling assemblies where Building Regulation compliance must be demonstrated.
• Clips into MuteClip Channel — no specialist tools required. The channel clicks directly into the clip body. Standard plasterboard fixing methods apply once the frame is in place.

Installation

Fix MuteClip XP clips to the underside of joists or structural substrate at the centres specified in the installation guide. Click MuteClip Channel into the clips to form the decoupled frame. Fix acoustic plasterboard to the channel using appropriate fixings — do not allow the plasterboard or any other element to make direct contact with the surrounding structure, as this will create a sound bridge and reduce performance. Seal all perimeter gaps with AC95 Acoustic Sealant.
