MuteClip® (Patent Pending) Concrete Double is our best most popular option for projects that require a ceiling soundproofing solution for concrete that is both high performing and space conscious at only 75mm. It creates fewer points of contact with concrete soffit ceiling using our MuteClip® which is composed of a dual density rubber in a galvanised metal case that performs like a shock absorber. The MuteClip® Channel then affixes to the MuteClip® and the new soundproof ceiling composing of two dense layers of  Acoustic Plasterboard 15mm and a layer of Tecsound suspends away from the concrete slab resulting in a vastly improved reduction of airborne noise. Particular focus is given on the problematic lower to middle-lower frequencies, as well as reducing impact noise and other forms of light vibration which are often problematic in concrete constructions.

Are you prepared?

  • Conduct prior sound testing or home testing to draw attention to any potential flanking paths (where sound takes an alternative route); 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® 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® is fixed to the bottom of the concrete soffit.
  • 200mm overlap on MuteClip® Channel with four self-tapping screws into the shoulders of the MuteClip® Channels.
  • The Rockwool RW3 is then pinned behind the MuteClip® Channel.
  • 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).

All of our systems contain a high level of mass. 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.

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.

Noise Reduction Guidance*

  • Television, light music levels
  • Clear Conversation
  • Impact noise issues and light vibration

 

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. 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 a loss of space giving to only 80mm, MuteClip® Concrete Double comes as one of our most desirable options for balancing the space lost, with the soundproofing qualities it gives to both airborne and impact noise issues from common noise issues in the home. With noise issues that range from airborne from day-to-day conversation to raised television levels, to impact noise of dropping of objects from time to time and walking on hardened flooring from above - this system will help to reduce those issues. One major point to consider in concrete constructions is that it is often found that Flanking Transmission is high in adjacent walls due to the sheer mass, especially where low frequencies noise issues are concerned. We would expect to see a 5-10dB improvement 25-50% reduction of noise issues as a guide, but again, low frequencies and excessive noise issues would require something more robust.

Lowering noise issues can often be difficult when they contain high amounts of low frequency sound energy: the use of subwoofer speakers, the popular soundbars and loud footsteps without any acoustic treatment or isolation from above because of Flanking Transmission in to the walls. Removing noise issues is subjective in that some are content with them reaching a background noise level, which is what all soundproofing systems aim to do in commercial and residential use - complete removal would require heavy isolation which is often incredibly difficult in the home without substantial cost.

When considerations of Flanking sounds have been checked and adequately soundproofed on the adjacent walls, Mute Clip™ Concrete Double can be specified for Part E Building Regulations for conversion projects and residential new builds, both internal dwelling and separate dwellings. It would be important to consider one of our acoustic over screed or under screed during the flooring process above to make sure that the right acoustic treatment and isolation has been given to reduce impact noise issues, which are often the primary issue in concrete constructions.

Resilient Channel does offer decoupling, but not to the same degree as MuteClip® and it’s Channel. The vulnerability in the Resilient Channels design lends itself to a range of potential errors in fixing that can affect acoustic performance. MuteClip® requires only a single fixing, and the Channel snaps on to each row of clip, it cannot be bend, over tightened to the point that it needs to be replaced or short circuited. Beyond this it is also superior in acoustic performance against low frequency sound energy, an important factor in the reduction of impact noise issues, and the reduction of airborne noise issues in excess of this range.

To when Acoustic Plasterboard is in contact with adjacent surfaces that are rigid, this lends itself to being subject to passing of vibration through Flanking Transmission - the aim is to keep as short a distance as possible so that there is no direct contact, abutting them tightly will short circuit both MuteClip® and Channel and will reduce it’s suspension. Leave a gap of this size and use a bead of Acoustic Sealant to reduce airflow in these areas.

MuteClip® and Channel leaves a void of 41mm in which is suitable for the installation of sound insulation of 25mm or 30mm Acoustic Mineral Wool. Do not use thicker sizes as this will create a path for sound to travel from the concrete substrate and first layer of Acoustic Plasterboard - short circuiting the MuteClip® and Channel's isolation properties

Any existing framework, plasterboard or other ceiling constructions would require removing prior to installation to ensure a safe fitting, electronics would also requiring extending to the new depth of the system which is 80mm.
