MuteMat® USF 650-03 is our highly effective acoustic under screed for soundproofing concrete flooring between the structural concrete slab and floating screed. Its high recycled content helps to reduce the carbon footprint while still retaining a consistent density, this assures that our material's acoustic performance and its longevity is upheld without fluctuation or fault.



  • Easy to install, roll out and tape joins
  • A moisture-resistant sheeting may be required during installation
  • Up to 23dB for impact* (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. (Details are available on the 'System Performance' tab above).


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 MuteClip®  Double Plus. We can provide Acoustic Modelling Data for estimating resultsCAD drawings of the MuteClip®  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.


MuteMat® USF 650-03 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.

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 prior to 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 prior to 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.
