What is screed and why should soundproofing materials be used in concrete structures?

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 .

Can I use MuteMat® USP 750-08 to soundproof timber floors?

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.

Do I need to adhere MuteMat® USP 750-08 to the concrete sub floor?

MuteMat® USP 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.

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® USP 750-08?

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® USP 750-08?

MuteMat® USP 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.

We supply a range of soundproof underscreeds depending on your requirements. These are high-quality, durable and reliable products designed to take high point loads and sit between the concrete slab and the new concrete screeding, helping to float the screed to greatly improve impact reduction. All of our acoustic under screed products, under the correct guidance, are suitable for achieving Part E Building Regulations. Our core products appear in our MuteRange.
