MuteClip LP Double – Ceiling Soundproofing

Ceiling Soundproofing

MuteClip LP Double

Take a look at the system’s features and benefits.


Hear the difference.

Play the video to hear the airborne sound difference before and after installing this system. For best results try to match the volume of the unreduced audio to the volume of the noise you’re able to hear.

The noise in the video has been digitally reduced to give you an idea of the sorts of results you could expect. Unfortunately, this is not a perfect science and your personal results could vary due to myriad reasons. However, we have found our customers prefer to hear a decibel reduction rather than read it!

We stand for quality, and we are proud of it.

If you don’t want to lose too much ceiling height but know you need to very high-performing soundproofing The MuteClip LP (low profile) Double may be your ideal choice.

In this system, the MuteClip LP is fixed to the side of the joists instead of belwo them to create a metal frame along with MuteClip Channel that sits just below the existing joist and maintains excellent soundproofing qualities.

It creates lesser points of contact with the joist ceiling using our MuteClip® LP which is composed of a dual-density rubber in a galvanised metal case that performs like a shock absorber, and this is bolted to a bracket that allows both MuteClip® and Channel to nest into the joists.

The MuteClip® Channel affixes to the MuteClip® LP and the new soundproof ceiling which is composed of two layers of dense Acoustic Plasterboard 15mm and Tecsound suspend 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.

Advice and installation

Our team are always a phone call away ready to offer advice and support. Our systems can be installed by competent DIYers but if you would like to work with an installer we have relationships with installers up and down the UK that we can put you in touch with.

  • Easy to install, no incorrect fixing or shortages, unlike standard Resilient Channel.
  • System thickness from the bottom of the joist 39mm
  • 10dB – 15dB estimated improvement for airborne noise and 20dB estimated improvement for impact noise* (where 10dB is a 50% reduction as perceived sound loudness).
  • Compliant with both Part E Building Regulations (England, Wales, Northern Ireland and the Republic of Ireland) and Building Standards Technical Handbook 2017 for Scotland for airborne and impact transmission.

Partition Measurements


Advanced Settings

Start Over
Ceiling Isolation Clip Calculator
Ceiling Stud Center

The ceiling joist center is the distance between ceiling joists measured from the center. The typical ceiling joist is 400mm. If you are working directly on a concrete ceiling we recommend using a 400mm spacing here also.

Ceiling Channel Center

The ceiling channel center is the distance between the MuteClip Channels. The typical channel center is 400mm. If you are working directly on a concrete ceiling we recommend using a 400mm spacing here also.

  • If you have multiple adjacent surfaces or partitions to soundproof input them individually. Not as a total m2 input as this will affect the results.
  • If you have windows, fireplaces or other fixed structures we recommend booking a call with us before purchasing.
Ceiling soundproofing calculator
Ceiling ‘Width’

For the calculator, the width of a ceiling is the measurement that runs perpendicular to your existing ceiling joists.

Ceiling Joist length

Joist length refers to the measurement that runs parallel with your existing ceiling joists.


A soundproofing system isn’t rocket science but sometimes figuring out which one is right for you can be challenging. Check out our FAQs, get in touch via our live chat, or give us a call to speak to a human.

With the MuteClip® LP, Low Profile attached to the side of the joist instead of the bottom, the total loss of head height is minimised as the clip and channel can now sit further up the joist, only requiring adjustment to meet the lowest point of the ceiling. You will want to make sure the initial plasterboard has a small isolation gap between it and the joist, contact will pass sound through and may cause vibration. Overall acoustic performance is not affected by the design and will remain the same as our standard MuteClip® Double. Flanking Transmission should always be addressed in each adjacent wall for if sound is found in those areas, this will affect overall performance, but as a general guide for the reduction of noise we expect to yield an 10-15db decrease for airborne and 10-20dB for impact transmission, so a 50-67% or a 50-75% reduction respectively.

We expect to see vast improvements to any of those noises that are created in typical households; day-to-day noise issues can often affect our daily lives even when a neighbour is only perhaps carrying out their regular routine. We have chosen the word block here to highlight that it is often used in acoustic, and is often also very difficult to achieve. The primary aim is to reduce its transmission to a background noise level. Those with hearing sensitivities of both a medical and psychological level will react to sound in far more acute ways, but even people without such ailments or disorders have their sensitivity to sound.

With Flanking Transmission addressed on adjacent walls, the acoustic values that MuteClip® LP Double achieves are in excess of Part E Building Regulation requirements for both conversions and new builds in the majority of cases. It is still wise to use an acoustic underlay above to reduce impact noise and to inquire about an acoustic partition design, something we can put together, to look at estimated results and outcomes with your proposed flooring and ceiling structure.

The MuteClip® LP offers very little error to be made during fixing, and it does take a little more focus on making sure the ceiling is straight in that the plasterboard is not in contact with the joist at any time, and that there is a gap big enough to deal with vibration and suspension. Resilient Channels offer no alternative for reducing head height, so if this is the concern, we would highly recommend the MuteClip® LP for best acoustic performance with minimal head height loss.

With direct contact of hard surfaces, such as abutting Acoustic Plasterboard to the adjacent walls – this creates an easy path for vibration to travel, inevitably short-circuiting both MuteClip® and Channel. With tight abutting this will lead to restriction of ceiling suspension, negatively impacting the acoustic performance of the system. Make sure you always to leave an isolation gap between these surfaces and run a bead of acoustic sealant down them through each layer to prevent air flow. Tecsound, on the other hand, can be in contact due to its ability to reduce vibrations and seal gaps.

The overall thickness of your joists will determine the resulting depth of Acoustic Mineral Wool you should look to install. Remember, MuteClip® LP will sit further into the joist and will not offer the expansion gap that is offered with the standard MuteClip® and Channel, With a typical joist depth found in most residences of 2×8 inches or 50.8 x 203.2, perhaps only 150mm total thickness of Acoustic Mineral Wool would be appropriate. We recommend leaving an air gap of at least 10mm from the MuteClip® Channel and the floor above, tightly compacting in additional sound insulation will harm acoustic performance.

Cornice, coving and all other decorative features often found in or near ceiling areas will require removal up until the final estimated depth of the new MuteClip® LP Double. The same goes for electronics – light fixtures, alarms or motion sensors; for example, these require the wiring extended to accommodate the new depths and locations, this work would be carried out by a registered electrician. Plasterboard or a Lath and Plaster ceiling would also need to be removed to allow the fitting of the MuteClip® LP.
