Specialist Acoustic Flooring Underscreed for Part E Building Regulations Compliance
MuteMat™ USP 650-03 is our thin and high performing acoustic under screed 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 a general acoustic over screeding product, view our MuteMat™ OSF-750 05 and MuteMat™ OSF 750-10 and for increased impact reduction in under screed applications our MuteMat™ USP 750-08.

- Suitable for concrete structures to effectively attenuate impact noise.
- A guaranteed consistent 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.
What is screed and why should soundproofing materials be used in concrete structures?
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.
Can I install MuteMat® USF 650-03 as a floor soundproofing option for over screed?
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.
Do I need to bond Mute Mat™ USF 650-03 with adhesive to the concrete subfloor?
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.
Do I require a damp proof membrane?
This will often be for the specifier to decide on whether it is required or not.
What is the point load and resulting compression of MuteMat® USF 650-03?
10 kN/m2 = < 7% loss of thickness.
15 kN/m2 = < 10.6% loss of thickness.
20 kN/m2 = < 14.3% loss of thickness.
How do I cut MuteMat® USF 650-03?
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.
