  • Weight: 7.8kg.
  • For: Great and small scale residential and commercial projects looking for soundproof under screeds.
  • Compliance: Compliant with both Part E Building Regulations (England, Wales, Northern Ireland and the Republic of Ireland).*
  • Installation: Please see our installation tab below.

Our pimpled under screed underlay specialised for controlling excessive noise issues in concrete structures.

MuteMat® USP 750-10 is our robust, mid-tier pimpled acoustic under screed resilient layer designed for achieving a high level of impact reduction between the floating concrete screed and structural concrete slab layers. its high performance comes from it's deviated pimpled structure which is found at both 5mm and 10mm - helping to secure minimum points of contact between the two layers. MuteMat® USP 750-10 maintains a low level of compressibility, even when subjected to high points loads making it suitable for a wide range of applications in residential, commercial and industrial structures, uniquely where particular low-frequency noise issues and machinery operation is concerned, this is tailored to reduce acoustic problems such as these.


  • 1m x 1m x 10mm (1m2)
  • Specialised as an acoustic under screed.
  • Suitable for concrete structures to effectively attenuate impact noise.
  • Can be installed under a wide range of floor finishes, with no requirement of an overlay.
  • Guaranteed consistency of thickness and density.
  • Does not deform, maintains efficiency long term under heavy loads.
  • Pre-fabricated recycled tire granule mat.
  • 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.

Although MuteMat® USP is high performing in concrete builds, it can also be implemented in other builds including timber to create a floating floor, with the additional benefit to lay floor finishes directly on top.

We are always looking for the best ways to describe to you the world of soundproofing through introducing guides that range from the basic principles of sound, how to best soundproof surfaces and what to look for, and how to understand acoustic test data, and this is only naming a few! We want to help you come to the right decision, so whether this is through the use of our guides or talking to a member of our team - we are here to help!


How to soundproof a floor

A combination of the following will always result in a much improved acoustic performance.


  • Mass: the addition of more substantial materials to reduce sound energy, for example, added layers combined with soundproof plasterboard.
  • Separation: breaking contact with the surface or surfaces through the use of acoustic isolation clips, or stud framing.
  • Damping: the reduction of vibration through the use of flexible, damping materials such as Tecsound.

MuteMat® USP 750-10 provides damping and separation, both very important in concrete structures for the minimising of impact noise. The mass is often sufficient in the concrete slab itself but is improved further with the separation of the screed layers mass applied on top. For projects that are expecting greater or excessive noise issues, combined with our MuteClip® systems on both walls and ceilings. 


In under screed projects, there are a few options available, and each looks to separate the structural concrete slab from the surrounding surfaces and to float the new screed. Screed is the 'wet' levelling finish either applied directly to a concrete slab, which is often a 'rough' aggregate finish that is uneven or to composite floor build ups, for instance, on top of an acoustic layer. Before applying liquid or flow screeds, each room must use a Perimeter Flanking Band around the perimeter so that your soundproof under screed, screed and your chosen floor finishes can butt up against it. This Flanking Band is to minimise contact with the walls, because of the screed finish is touching it is going to reduce the floors flexibility to deal with impact noise or vibration and transfer through this path through Flanking Transmissionall floor layers need isolation. Then, depending on what your project requires, an acoustic under screed is installed, and you will find this type of soundproofing in a lot of new builds, including residential complexes and in areas containing large machinery or gymnasiums.

This product is part of the following systems:

Concrete constructions are made up of a structural concrete slab which is blended up of sharp, uneven aggregates - leaving a rough finish, a screed layer is then applied over the top to level out the unevenness leaving a smooth finish. In most cases, and especially in large residential structures, before the screeding stage most will want to include in their specification a sound proof under screed to float the screed away from the structural concrete - helping to sound insulate the floor from impact noise. Concrete is very effective at soundproofing against airborne noise because of the sheer mass it presents, impact on the other hand noise travels greater distances and because of it's dense molecular construction and amount of direct contact it has with the adjacent surfaces - flanks through these connected paths by way of Flanking Transmission.

MuteMat® USP 750-10 deviates between two levels, leaving a pimpled structure which gives it minimal points of contact between the floor finish and the sub-floor, and because of this it can be used  to soundproof against impact noise in timber structures.  It is recommended to cross-fix two layers of 6mm ply, glued and screwed to the top of the MuteMat® USP 750-10 to give a level and stable floor. It can also be used in soundproofing small home gym projects in conjunction with our Gym Soundproofing range where timber structures could suffer from excessive impact noise, it can be used in recording studios and other audio focused suites too along with cinema rooms where bass frequencies are to be expected in abundance and can travel through materials that are in direct contact, these require separation.

Mute Mat™ USP 750-10 requires no adhesive in structural concrete and screed scenarios, it is simply rolled out and taped - ready for a screed layer. For direct application of floor finishes like engineer wood, laminate or luxury vinyl tile, we would recommend the installation of two layers of 6mm ply cross-fixed with the glue and screw method to leave a stable base.

This will often be for the specifier to decide on whether it is required or not.

10 kN/m2 = < 7% loss of thickness.

15 kN/m2 = < 10.6% loss of thickness.

20 kN/m2 = < 14.3% loss of thickness.

MuteMat® USP 750-10 is best cut with a fresh Stanley blade and a straight edge or metal ruler, always cut away from your body and behind the straight edge.
