CMS Acoustics Solutions - Regupol E48 scores top marks for Oak Tree Developments

Ahead of the government’s Code for Sustainable Homes, Oak Tree Developments has demonstrated how easy it can be to achieve top marks for sound insulation by installing Regupol E48 - a high performing screed isolation material - at its new build apartment project in Idle, West Yorkshire.
Available exclusively from CMS Acoustic Solutions, Regupol E48 is the only Robust Detail (RD) approved system for beam and block floors (E-FC-6), the floor type installed by Oak Tree.
Although strictly a pre-completion testing project, as not all internal walls were continuous from the foundations to the roof, Oak Tree built to RD guidelines to optimise acoustic performance.
By doing so, the Oak Tree apartments obtained an airborne rating of 57dB and impact of 47dB. Under the Code for Sustainable Homes, this would have achieved four points – the maximum the code permits for sound insulation performance.
Compatible with all types of floor screed, Regupol E48 is suitable for use in most new build constructions. Simple to install, Oak Tree used Regupol E48 to isolate 200mm-deep Collier and Henry beams from the main structure of the building.
Carl Darren of Oak Tree Developments, elaborates: “Favouring the RD route to project completion, we used Regupol E48 because it was the only under screed treatment for beam and block floors which had RD approval.
“Due to certain project irregularities, we were not able to formally register with RD, but we did want to ensure the dwellings would be fit for purpose and provide future occupants with a decent standard of living.”
To achieve the overall high performance that Oak Tree required, CMS Acoustics also recommended the installation of Regupol 6010XHT acoustic isolating strips. These were used to prevent flanking sound transmission by isolating the internal blockwork and perimeter construction from the structural steelwork.
David Holder, director of CMS Acoustic Solutions, comments: “The test results achieved at the Oak Tree apartments were well in excess of the minimum required by Robust Details (50dB). Furthermore, achieving what would have been rewarded top marks under the Code for Sustainable Homes underlines the importance of planning for any future development.
“This is a fine example of a project which has been built against practical living criteria as opposed to just meeting minimum regulation standards.”
Manufactured in Germany by BSW, the complete Regupol range is available exclusively in the UK through CMS Acoustics.
CMS Acoustics has a proven record in introducing new solutions for Part E compliance. It was the first to provide a UK Tiling Association (TTA) compliant acoustic tiling system with Regupol Acousti-Tile, as well as delivering access to the only RD approved system for beam and block floors.
CMS Acoustics is part of the CMS Group, which also includes CMS Vibration Solutions. Specialising in anti-vibration and structural isolation products for construction and industrial applications, CMS Vibrations has access to the full range of anti-vibration and structural isolation solutions through exclusive partnerships with manufacturers and market-leading systems.
