This was the first ever build to incorporate acoustic wall insulation in a party wall.
MFS Comment
On this project you could not use much more aircrete if you tried. MFS used aircrete for the entire inner skin of the development and for the first time on a commercial development we also used the H+H flooring system with Celcon Foundation Blocks. We specialise in Rå Build and know how easy and fast it is to get an aircrete shell built from dpc, but we were pleasantly surprised with the foundation and floor products. We found the floor very quick to lay great to work off and incredibly flat, providing an excellent base for the rest of the construction.

Client Testimonial
We were pleased with the Rå Build approach because having the one shell contractor simplified the process for getting the site underway within agreed time frames. The speed of build is remarkable and in fact the watertight shells were ready so quickly we had to be alert to keep up. We found the Thin-Joint walls provide a very solid and true base for following trades.
Comprised of a Celcon thin joint untied separating wall with a 75mm cavity filled with Isover acoustic insulation, finished with plasterboard on dabs. No render/parge coat on the wall surface was considered necessary with this design. This was aimed at meeting a minimum acoustic performance of 50dB DnTw + Ctr, 5dB above that required by the building regulations, to attract 3 credits under the Code for Sustainable Homes (CfSH). Airborne sound tests undertaken on the properties resulted in performance value of 55-57dB, which in fact is even better than the highest possible credits achievable under the CfSH of 4 credits, where a minimum value of 53dB is required. These are the highest sound reduction test results we have ever achieved.
