MuteMat® OSF 750-10 is our best performing and most robust resilient acoustic underlay of our MuteMat® OSF range for soundproofing concrete flooring against intrusive impact noises. It's highly recycled content helps to reduce the carbon footprint while still retaining a consistent density, this assures that our material's acoustic performance and it's longevity is upheld without fluctuation or fault.



  • Easy to install, roll out and tape joins (an adhesive may be required, please see below under installation).
  • System thickness from the existing floor 10mm

  • 23dB ΔLw for impact reduction (details are available on the 'System Performance' tab above).
  • 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 impact transmission.


For optimum acoustic performance, installation with our MuteClip® System variations is recommended on adjoining ceilings to improve both impact and airborne noise.


At iKoustic our team can help you from start to finish, and with the use of our MuteMat® OSF 750-10, we can provide Acoustic Modelling Data to estimate results, and can provide fantastic rates on those projects so that you feel the right choice has been made. We also offer Acoustic Testing for existing structures as well as Part E Building Regulation testing and another specialised acoustic testing for projects that include: Gyms and Nightclubs or even Residence that require or seek increased acoustic performance for improved living quality.


MuteMat® OSF 750-10 is part of iKoustic's MuteRange core - these are products that 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.

Making sure you are prepared

  • Depending on your floor finish, you may require additional adhesives which you can view below
  • If using after freshly poured concrete/screed, please allow the subfloor to cure before laying to avoid any complications with the installation.
  • Loss of space 5mm

How to Install

MuteMat® OSF 750-10 requires a Perimeter Edging Strip around the perimeter of the room to allow floor layers to adjoin to, helping to reduce the effect of Flanking, which can often be the cause of failures regarding Part E Building Regulations. You will also want to use a Blue Cloth Tape to tape the joins together.


Bonding to Substrate

  • F-Ball Styccobond F3 can be used to adhere MuteMat® OSF 750-10 to an absorbent substrate
    • if primer is required, the recommended primer for most substrates is F-Ball P131
  • If anhydrite screed has been laid, the laitance must be cleared before applying any primers or adhesives
    • The recommended primer for anhydrite screed is F-Ball P121
  • Smoothing compounds and latex screeds are usually designed to accept an adhesive applied directly

Wooden flooring finish

  • F-Ball Styccobond B95 can be used to bond timber floor finishes to MuteMat® OSF 750-10


Luxury Vinyl Tile

  • F-Ball Styccobond F46 can be used to bond vinyl floor finishes to MuteMat® OSF 750-10


Ceramic / Porcelain Tiles

  • MuteMat® OSF 750-10 to concrete/screed substrate, prime the substrate first with roller coat of ARDEX P82, allow to cure, then bond MuteMat® OSF 750-10 using either ARDEX S 28 or ARDEX X 7001 Mictrotec.
    • If bonding MuteMat® OSF 750-10 to a timber substrate, Ardex AF200 should be used.
  • When you come to lay the tiles, you should prime MuteMat® OSF 750-10 with ARDEX P82, then bed the tile into either ARDEX S28 or ARDEX X 7001 Microtec.
  • Flexi grout should be considered



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 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 impact transmission featured in the Building Standards Technical Handbook 2017 for Scotland, 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.

MuteMat® OSF 750-10 | Concrete Floor Soundproofing

One of the most common issues between neighbours is from to disturbance through the noise, and this can often lead to a tense environment and something that is only solved by having the right soundproofing in place, and with cooperation where possible on the outcome. To where impact noise is the primary concern, our MuteMat® OSF 750-10 offers a substantial reduction of noise in slim-line solution, offering approximately ∆Lw 23dB reduction taken from a 140mm concrete floor slab, this is over a 75% reduction of noise issues for impact noise.

Acoustic tests made on a 140mm concrete slab yield a reduction figure of ∆Lw 23dB, which for the majority of cases would yield the acoustic performance required across the board for both conversions and new builds regarding impact sound insulation. If you are looking to specify for an existing concrete structure, we would recommend carrying out an acoustic test before gather results of both airborne and impact performance to see what requires achieving. With specifications that require planning approval for a structure has not been built, we can create digital representations of acoustic partitions to see what guide of results you would expect in block and beam, pre-cast and cast in-situ concrete builds.

It would often be accompanied with our MuteClip® soundproof ceiling systems to increase performance for airborne noise and any impact noise issues that are found to be high, and for reducing structural vibration being located at the ceiling level.

We would recommend carrying out the same processes as above due to the acoustic requirements set out by the Scottish Building Regulations being much higher for both airborne and impact in new builds and conversions. It would most likely be required to implement a soundproof ceiling below to meet both the impact and airborne reduction values.

Far larger machinery that requires fixing into the flooring, the MuteMat® OSF 750-10 would not fair well as there would be multiple points of contact made to where vibration will travel. Lighter weight machinery and other equipment that can be set on top of MuteMat® OSF 750-10 would fair better in mitigating structural borne vibration.

If the structure and its plant machinery are yet to be installed - you would be best to look at using a floating screed construction with our MuteMat® USP range to gain the best separation possible.

If the room you are looking to build or convert shares a concrete foundation or is in proximity to other structures - MuteMat® OSF 750-10 would be a great addition to reduce impact noise from instrumentation and helping to decouple amplifiers and subwoofers from creating structural borne vibration - without any floor soundproofing you run the risk of these issues running under the wall soundproofing. When soundproofing cinema rooms or audio studios from above, it would be best to couple with a ceiling system underneath to best mitigate noise issues - airborne noise may not be sufficiently reduced with the concrete's mass alone.

You can find all of our current information on this acoustic overscreed and its compatibility from the results below with use in conjunction with underfloor heating systems

Thermal Conductivity = 0.113 W/mK

Thermal Resistance = 0.094 m²K/W

Temperature Stability = -35°c to +100°c.

With a 10mm increase, it may not require any alterations around the perimeter of the room, but depending on new floor layers some skirting may require moving and doors trimmed to a more suitable height. But, it certainly can be installed retrospectively and is an excellent option for anyone looking to install new hard floor finishes to replace a carpet perhaps.
