MuteMat USP 650-03 is our thin and high performing acoustic underscreed resilient layer for reducing impact noise between the floating concrete screed and structural concrete slab layers - as a dense and robust product it maintains a low level of compressibility, so even when it is subjected to high points loads - it maintains it's acoustic performance, thus making it suitable for residential and commercial use without increasing floor heights drastically. If you are looking for an general acoustic overscreeding  product, view our MuteMat OSF-750 05 and MuteMat OSF 750-10 and for increased impact reduction in underscreed applications our MuteMat USP 750-08.



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.

How to Soundproof a Floor

With soundproofing screeding layers you will require a dense acoustic underscreed product such as our MuteMat™ USF. 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 okay results initially but as it crushes overtime any 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.

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:

In concrete constructions there will be a structural concrete slab which is constructed of sharp, uneven aggregates that leaves a rough finish, and a screed layer that is applied over the top for levelling out the structural concrete to leave a smoother finish. In most cases, and especially in large residential structures, before the screeding stage most will allow for a specification of under screed sound proofing materials to assist in floating away the screed from the structural concrete - helping to sound insulate the floor against impact noise.

As the MuteMat™ USF 650-03 has a lesser density than our over screed options - which is used to alleviate impact noise issues in screeding applications, it is not the best option to use as an overscreed as it cannot receive hard floor finishes directly because of it's compressible properties.

We would recommend looking at our MuteMat™ OSF range for suitable options for over screed floor sound proofing.

Mute Mat™ USF 650-03 requires no adhesive, it is simple rolled out and taped -  overlaid with DPM if required, and ready for a screed layer.

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 650-03 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.
