Joist ceiling soundproofing option minimising the loss of height while giving the same performance as our standard MuteClip®. An upgrade to MuteClip® LP Single for reducing airborne and impact noise.
MuteClip® (Patent GB2580959) LP Double is a popular option for projects that require a ceiling soundproofing solution that is both high performing and reduces head height loss without compromise of acoustic performance. 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.
MuteClip® LP Double is available for specification on a wide range of projects that include large scale residential builds, commercial properties for increased privacy, and even audio recording and audio editing environments that are limited in space. This system is also suitable as a retrofit for those looking to improve existing properties, perfect for soundproofing the home.
Projects where you are specifying the use of an acoustic system our team can help you from start to finish and with the use of our MuteClip® LP Double. We can provide Acoustic Modelling Data to estimate results, CAD drawings of the MuteClip® LP and Channel to aid visualisations, and fantastic rates so that you feel you're making the right choice. We also provide Acoustic Testing for existing structures as well as Part E Building Regulation testing and additional acoustic testing options for projects that include: Gyms and Nightclubs or even homes that require or seek increased acoustic performance for improved living quality.
MuteClip® LP Double contains components from our MuteRange core - these are products that have been subjected to stringent testing in both laboratory and real-world environments providing the best possible solution for the purpose with a result you can trust.
You can find out more about our all-encompassing MuteRange by clicking on the icons below or get in contact with iKoustic today.
We have provided a detailed blog on the use of our MuteClip® System against the 'Additional Costs of Resilient Channel.'
"To make you aware of the potential issues and additional costs Resilient Channel can leave within the project, we have provided some brief points to review before proceeding with this method."

Installation is based on a 400mm - 800mm diamond spacing. MuteClip® Channels would also installed with a 400mm spacing with one located 100mm from top and bottom. Please see installation guides for more information.
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.

All of our systems contain a high level of mass, and if there are any structural concerns, you will want to consult a Structural Engineer to discuss your requirements.
*Our Typical Performance Results and Noise Reduction Guidance are provided to indicate the results that have been achieved in previous tests but are not guaranteed to a specific site as multiple factors can affect this.
*Our guide price includes all materials and ancillaries required
We endeavour to display the most up to date testing and to manage expectation as best as possible; please do contact us to discuss your requirements

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.
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 2x8 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.
