Floor Soundproofing

MuteMat USP 750-08

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

26 dB ΔLw Impact Reduction*

Noises like footsteps on wood flooring and washing machines.

8 mm additional System Height

The height added to your floor after the system is installed.

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

A pimpled concrete under screed that offers greater protection against impact noise and vibration by helping to float the screed finish. For noise sensitive structures and Part E Building Regulations.

MuteMat® USP 750-08 is our robust, highly effective pimpled 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.

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, roll out and tape joins.
  • Increases floor height by 8mm
  • A moisture-resistant sheeting may be required during installation.
  • 26dB* for impact reduction  
  • 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. 


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.

MuteMat® USP 750-08 features both a flat surface to the receiving on the screed and a pimpled underside which leaves fewer points of contact made between the screed and structural concrete slab, this drastically improves impact transmission and helps to reduce low-frequency energy through structural vibration also. The floating screed is fitted with no points of direct contact, even with the walls as this requires a perimeter detail that both MuteMat® USP 750-08 and screed is abutted to – to prevent flanking noise. Its noise reduction figure is measured at ∆Lw 26dB – this will vary on your structure and thickness of screed.

MuteMat® USP 750-08 is soundproof over screed compatible with all concrete structures including block and beam, precast and cast in-situ concrete. No bonding is required to the substrate and comes in a roll, one that is simply rolled out to the edges of the room to abut to the perimeter edging strip and taped at all joins.

For details on screeding and thicknesses you will want to look at our current information on compression set percentages with what would be best suited, with floating unbonded screeds it is likely that a 50-65mm thickness is required for general usage, but with industrial complexes, plant rooms and the harbouring of heavy machinery and use of fork lists – a much thicker screed would be desirable to prevent any cracking.

Depending on your total weights and what noise levels are expected to be generated will determine on both screed thickness and correct soundproof under screed.

Manufacturing facilities, engineering plants and even automobile testing facilities all often produce overwhelming levels of sound energy that focuses heavily in the low-frequency range, sound waves of this type tend to travel great distances and when subject to solids – will move even further and cause structural borne vibration. The internal of any room that harbours these noises need a significant amount of suspension in regards to acoustic materials in the room – lesser points of contact with the main structure. We can help review your plans of construction and the potential noise sensitive environments in the vicinity by carrying out a Noise Impact Assessment.

Depending on the proposed areas to what level of impact noise is expected and any localised noise sensitive areas, this will determine what level of soundproofing is required and what soundproof under screed is most appropriate. MuteMat® USP 750-08 would most likely have its place in areas of spin-cycles and treadmills to where substantial impact expected through vibration created with increased footfall. In high sensitive noise areas, a combination of different materials would often require to be implemented to avoid potential local complaints and disturbances. We can help carry out Noise Impact Assessments for the introduction of a new Gym.

As we carry out further tests, we have yet to test for Thermal Resistance, but on our product data sheet, you can find information for Temperature Stability and Thermal Conductivity. Once we have this, we will update our information accordingly.

Yes of course – it is the same process as a new build, as long as your structure can safely support the additional weights. You lay it by simply taping the joins of MuteMat® USP 750-08 and abutting to the perimeter detail along with the new screed.

Important Information

Our products 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, you can view their variants on our ‘Featured Systems’ tab.

Delivery information.

If you place an order online it’s likely we will call to discuss delivery to make sure it runs as smoothly as possible. Deliveries can arrive on a large vehicle. If there are access issues or HGV restrictions, please do let us know in advance as our website options are given in good faith of no restrictions. All of our deliveries must be signed for so you will need to ensure someone is on the premises on the day of delivery.
