MuteClip®(Patent Pending) XP Double is a popular option for projects that require a ceiling soundproofing solution that is both high performing and can accommodate varying joist depths as well as differing ceiling heights without resulting to additional joist levelling or ad-hoc methods of installation. It creates fewer lesser points of contact with the joist ceiling using our MuteClip® XP which is composed of a dual-density rubber in a galvanised metal case that performs like a shock absorber and this is bolted to an extension bracket that allows for an additional 100mm of spacing for accommodating the joist heights. The MuteClip® Channel affixes to the MuteClip® XP and the new soundproof ceiling which is composed of two layers of dense Acoustic Plasterboard 15mm and Tecsound suspends away from the ceiling joists. What this ultimately results in is a vastly improved reduction of airborne noise, especially in the more problematic lower to middle-lower frequencies, as well as reducing impact noise and other forms of light vibration.

Making sure you are prepared

  • Conduct prior sound testing or home testing to draw attention to any potential flanking paths (where sound takes an alternative route), and this will be an essential part of making sure you have the best soundproofing in place and managing what is possible to achieve, our team can help guide you on this.
  • You will need to make sure you are fixing MuteClip® XP direct into the joist without any obstruction
  • To lay Acoustic Mineral Wool between any adjacent stud framing or cavity walls to help reduce flanking transmission


How to Install

Installation is based on a standard 400mm  joist spacing, and we recommend staggering the MuteClip® at 400mm in a grid configuration with a MuteClip® at each end. MuteClip® Channels would also installed with a 600mm spacing with one located 100mm from top and bottom

  • MuteClip® XP fixed to the side of the joists.
  • 200mm overlap on MuteClip® Channel with four self-tapping screws into the shoulders of the MuteClip® Channel, running parallel with the joists.
  • Rockwool RW3 between joists.
  • The first layer of Acoustic Plasterboard fixed on to MuteClip® Channel with self-tapping screws (leaving a 2-5mm gap from any adjacent surfaces and using acoustic sealant).
  • A layer of Tecsound adhered with self-adhesive backing to Acoustic Plasterboard.
  • The second layer of Acoustic Plasterboard fixed on to MuteClip® Channel with self-tapping screws (leaving a 2-5mm gap from any adjacent surfaces and using acoustic sealant).
     

 

Alternatively, we provide Acoustic Installation across the UK to fit all of our systems - they come with a wealth of experience in the field so you can feel comfortable that the right installation methods are being carried out.

Compliance with Part E Building Regulations and Scottish Building Regulations
 

  • When installed under the correct guidance this system is compliant with the required acoustic values for airborne and impact transmission featured in Part E Building Regulations; these are applicable across the UK, excluding Scotland (England, Wales, Northern Ireland) and the Republic of Ireland. We would advise conducting a Sound Test to survey any planned conversions in existing properties before concluding on an Acoustic System.
     
  • It is also compliant with the required acoustic values for airborne and impact transmission featured in the Building Standards Technical Handbook 2017 for Scotland, and we would advise conducting a Sound Test to survey any planned conversions in existing properties before concluding on an Acoustic System. Scottish Building Regulations contain higher targets than that of Part E, and our Legal Requirements section has the required acoustic values.
     

  • For additional guidelines and requirements for non-residential buildings; for example, Gyms, Nightclubs and Industrial focused purposes, please do contact us so we can discuss your available options.

The extended profile of the MuteClip® XP assists in creating a soundproof ceiling solution that can be built into uneven joist ceilings without the need for any structural alterations by fitting on the side of the joist and allowing for 100mm distance between two points. Not only is this a perfect way to not add installation costs to a final project, but it does not alter in acoustic performance, they are the same performance figures to the standard MuteClip® option. You will need to take care to make sure that the Acoustic Plasterboard layers are not in contact or too close to the joists at the final levelling as this could cause impact noise and vibration to travel into the board - reducing the ceilings isolation properties and performance.

All common household neighbour and internal noise issues that are often found to be problematic are reduced with our MuteClip® XP Double system. We would expect to see improvements for all impact and airborne noise issues to where they are all brought down to a background noise level - although Flanking Transmission down walls should also be addressed with a robust ceiling soundproofing solution in place, weakened stud frame walls and walls with dot and dab plasterboard fitting will leak sound. Hearing is also a subjective measurement into where sensitivities ranging from those stemming from medical conditions and other hearing or psychological ailments can also be at play in reviewing the soundscape.

When the assessment of conversion is taking place for single dwellings converted into multiple houses - there are a range of sound paths that require treatment, especially if no existing soundproofing has been put in place. It is therefore vital that adjacent walls are reviewed and addressed accordingly as a ceiling soundproofing solution will often be negated from these paths, and leading to a failure in acoustic testing. With these addressed the MuteClip® XP shows acoustic results of surpassing values across the board for Part E Building Regulations. For proposed timber structures that require approval against the acoustic values in Part E, we can create partition designs with your floor and ceiling structure in place to evaluate possible outcomes with impact and airborne noise.

Resilient Channels also provide decoupling of structures

Resilient Channels do not offer a ceiling levelling option like our MuteClip® XP does, which is a bonus for anyone looking to create a single ceiling structure that features structural twists and bends.

The importance of creating isolation gaps to reduce Flanking Transmission is significant here in that the Acoustic Plasterboard layers should not be in contact with the adjacent walls for any vibration detected in these areas will move back into the boards, short-circuiting the suspension provided by the MuteClip® XP and Channel. If the Acoustic Plasterboard layers are tightly abutted against the wall, it will also reduce the suspension by creating resistance - reducing the systems movement to dealing with impact noise and low frequencies.

The total thickness of Acoustic Mineral Wool relies on the thickness of joist - to which can vary depending on loading requirements and span of the room. A typical joist depth found in most residences of 2x8 inches or 50.8 x 203.2, so a total thickness of 150mm of Acoustic Mineral Wool should be installed. It is recommended to leave an air gap of at least 10mm from the MuteClip® Channel and the floor above, tightly compacting in additional Acoustic Mineral Wool or any other type of insulation will reduce the system’s performance.

For anything within the depth of the new soundproof ceiling - ceiling and wall features such as cornice, coving or non-structural ornamental features should be removed before installation and electronics - light fixtures, alarms or motion sensors, for example, should be disconnected and any wiring extended to accommodate new depths. Plasterboard or a Lath and Plaster ceiling would also need to be removed to allow the fitting of the MuteClip® XP.
