MuteMat™ USP 750-08 is our robust, pimpled acoustic underscreed resilient layer designed for achieving a vastly improved impact reduction between the floating concrete screed and structural concrete slab layers; it's high performance comes from it's deviated pimpled structure which are found at both 8mm and 4mm - helping to secure minimum points of contact between the two layers. As a dense and robust product it maintains a low level of compressibility and when subjected to high points loads it maintains it's acoustic performance making it suitable for a wide range of applications in residential, commercial and industrial structures - especially where particular low frequency noise issues and machinery operation is concerned, this is tailored to reduce acoustic issues such as these.

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 direct on top. If you are looking for an general acoustic overscreeding  product, view our MuteMat™ OSF-750 05 and MuteMat™ OSF 750-10.



MuteMat™ USP 750-08 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.

How to Soundproof a Floor

With soundproofing screeding layers you will require a dense acoustic underscreed product such as our MuteMat™ USP. Due to the dense molecular construction and high mass of concrete this results in impact and low frequency noise issues travelling further,  a material with a high compressibility will present satisfactory results initially but as it crushes overtime the majority of the acoustic performance will be lost resulting in costly remedial works. Depending on your requirements it may be necessary to couple with our MuteClip™ System ceiling range to ensure an increased impact performance and airborne performance, we have a range of options depending on what your project is aiming to achieve, as well as considerations regarding space lost.

For Gym Soundproofing we suggest combining MuteMat™ USP with our DuraSound range for best acoustic performance.

If you are uncertain on the current acoustic performance, we would recommend our Acoustic Testing service to give us a clear view of what the structure currently performs at and what materials you would likely require in order to meet regulations or guidelines, and in some cases this could even reduce costs in specifying an alternative material that is more suited for your requirements.

This product is part of the following systems:

Flooring constructions in concrete structures are made up of a structural concrete slab, often rough, uneven and not suitable for applying floor finishes - and a screed layer that is applied to create a level and much smoother finish. In large concrete structures, especially where there are many dwellings that can cause disruption, it is important to specify the use of a sound proof under screed material to reduce impact and vibration transfer to minimise disruption - the MuteMat™ USP 750-08 is a pimpled product that helps to reduce points of contact between screed and structural concrete to assist in floating the screed finish. Although concrete is very effective at reducing airborne noise issues because of its substantial mass, impact noise will tend to travel further and flank through any connected paths because of the dense molecular structure of concrete and the amount of direct contact, this is called Flanking Transmission.

MuteMat™ USP 750-17 has a deviated, pimpled finish which gives it minimal points of contact between the floating floor and the sub-floor, and because of this it can be used on a timber structure to treat impact noise issues. It is recommended to cross-fix two layers of 6mm ply, glued and screwed to the top of the MuteMat™ USP 750-08 to provide a level and stable floor. Possible uses could be in conjunction with our gym soundproofing products for small home gym projects - where timber structures could suffer from excessive impact noise, and even in recording studios and other audio focused suites along with cinema rooms where separation with the structure is important to reduce vibration from bass frequencies.

Mute Mat™ USF 750-08 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 glue and screw 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™ USF 750-08 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.
