MuteClip® (Patent Pending) Double is our most popular option for projects that require a ceiling soundproofing solution that provides high acoustic performance and is space conscious with only a 75mm loss of space. It creates fewer points of contact with joist ceiling using our MuteClip™, which is composed of a dual-density rubber in a galvanised metal case, acting as a shock absorber. The MuteClip® Channel affixes to the MuteClip® and the new soundproof ceiling which is composed of two layers of dense Acoustic Plasterboard 15mm and Tecsound suspends away from the ceiling joist. 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 immediate vibrations.

 

 

  • Easy to install, no incorrect fixing or shortages unlike standard Resilient Channel

Are you 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 directly into the brick/block work and not fixing over existing plasterboard (this may require levelling before installation)
  • To lay Acoustic Mineral Wool between flooring and ceiling joists to help reduce flanking transmission


How to install

Installation is based on a 600mm spacing, and we recommend staggering the MuteClip® at 1200mm in a diamond 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® fixed to the bottom of the joist
  • 100mm overlap on MuteClip® Channel with four self-tapping screws into the shoulders of the MuteClip® Channels, running perpendicular.
  • 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.

Our MuteClip® Double is our most popular option for when soundproofing is required at home, or in the workplace for it has all the acoustic qualities that make for a highly effective system. MuteClip® and Channel offer a great deal of suspension and decoupling from the structure which offers high performance against raised noise levels by tackling low-end frequency and structural borne vibration such as impact noises from footsteps. The mass provided is a triple ply consisting of Acoustic Plasterboard and visco-elastic membrane - Tecsound, which is to reduce airborne noise transmission on the ceiling partition. The performance will always differ from structure to structure and will vary room to room in a single building for there are construction details and build qualities that lend heavy to how a specific room will perform acoustically. Flanking Transmission should always be addressed in equal measure to the walls if it is found in those areas, but as a general guide for the reduction of sound, we expect to yield a 10-15db decrease for airborne and 10-20dB for impact transmission, so a 50-67% or a 50-75% reduction respectively.

As both common noise issues to the home and workplace, MuteClip® Double would assist in reducing these to a near background noise level (depending on the intensity of the sound). You should bear in mind that hearing and noise levels are subjective, and some may find that even though you have turned off all your appliances and sit in a near on silent room that you can still hear it. The aim is to reduce it down to background noise levels as a goal, but these sensitivities can often be at play, especially if you have been subject to them for an extended period. When investigating soundproofing for your space, check for Flanking Transmission down walls, especially where dot and dab or stud frame walls are concerned.

When flanking paths have been adequately assessed and soundproofed if noise is found to be travelling down them - the MuteClip® Double offers acoustic values that surpass Part E Building Regulations and has done on multiple occasions in this build up - both for conversion projects and new build structures. We can offer partition estimations for new builds with suggested floor and ceiling makeups, but it is always wise to look at installing an acoustic underlay above for the treatment of impact noise at the source or look to break contact with the floor the wall connection due to flanking transmission for impact found in these areas.

MuteClip® and it’s Channel is designed for a single fixing per clip and the Channel is clipped into these, this is so that it is easy to install with no incorrect methods of fixing, suitable for DIY enthusiasts to architects and specifiers working on a broad range of projects. The issue with Resilient Channels is that it takes only a small error to render its acoustic performance as useless, and with a failure of acoustic test or uncertainty of why there are issues with soundproofing - the system must be taken down and restarted, costly across time and to the final budget. The MuteClip® and Channel also offer a raised level of reduction in the lower frequencies, essential for the attenuation of low-end sound energy and structural borne vibration.

When rigid surfaces are in direct contact with one another, they can pass through vibrations with ease, so if the Acoustic Plasterboard layers are abutted tightly to the adjacent walls, any flanking sound found in these areas will move into the plasterboard and short circuit the MuteClip® and Channel’s isolation. Tightly abutting will also lead to reducing the ceiling’s suspension that again, both MuteClip® and Channel give - which is essential for the reduction of low-end sound energy and structural borne vibration.

Depending on the span of your room will often determine the thickness of joist that you have, the standard joist size for the majority of residential buildings is 2x8 inches or 50.8 x 203.2, so with this example, we would recommend the use of two slabs of 100mm thick Acoustic Mineral Wool to double up as 200mm. Do not look to use any more here for compression made between the MuteClip® Channel, or Acoustic Plasterboard and the underside of the floor above will short circuit the system. With thicker joist sizes, look to make sure there is 10mm air gap at least either side, more significant air gaps are okay, but sound insulation material is required to stop the cavity from creating resonances and lending to ease of flanking sound.

All decorative features such as coving and cornicing will require removal either prior or during the installation, and any existing plasterboard will need removing too. Lath and plaster ceilings will often require removing to make sure that there is a secure fit, but often these are installed over the top of due to the process of removal - which is the better option of the two begins it means we can treat the cavity beyond it. If you are looking for an acoustic installation team we can provide all the above for you - we would need to factor this into the overall costs during our quotation. Electronics such as motion sensors, light fixtures and alarms will all need extending by an electrician prior and made safe for any installation team to pull through the required insertion holes made in the system.
