Innovative Sound Reducing Membrane Part of Roof System at Mayfair Scheme

CMS DANSKIN ACOUSTICS has supplied an innovative sound reducing underlayment, designed specifically for external use, as part of the roof systems at the prestigious new 38 Berkeley Square development in Mayfair, London.

When complete in September 2024, 38 Berkeley Square will provide 7,897m² of office space over 9 upper storeys plus retail space at ground and lower ground floors and terrace gardens.

The new build scheme is being developed by Berkeley Estate Asset Management, the main contractor is the Mace Group and the architects are Piercy & Company.

Mayfair Development

1,425m² of ‘REGUPOL sound and drain 22’ have been incorporated to counter vibration and noise from rooftop plant, rain and footfall. This acoustic product achieves sound insulation levels of 28 to 37dB. Developed for use on rooftops, terraces and balconies, it has a dimpled profile underside to give good drainage and water flow capacity and is rot-proof.

‘REGUPOL sound and drain 22’ was selected for the project, satisfying the acoustic performance specification developed by acoustics consultants Clarke Saunders, which took into account the location of two air source heat pumps and an air conditioning unit on the roof deck and the demanding requirements for limitation on sound transfer into the offices below. CMS Danskin Acoustic’s technical team advised on materials to meet the criteria set.

Supplied to the scheme’s roofing system provider Radmat, ‘REGUPOL sound and drain 22’ was incorporated as part of both the porcelain tiled roof terrace build-up above the cross laminated timber (CLT) deck and the planted green roof. Installation was undertaken by All Metal Roofing.

“The Berkeley Square project is just the type of scheme for which ‘REGUPOL sound and drain’ has been developed,” said Paul Absolon, Technical Director, CMS Danskin Acoustics.

Matt Sugden of Clarke Saunders Acoustics said, “We have been involved in numerous projects on which Regupol products have been successfully used to meet onerous acoustic requirements. This is our first experience of the ‘sound and drain’ product, but we have utmost confidence in Paul and his team and are confident that this system will perform as expected.”

Innovative Sound Reducing Membrane

Made from recyclate, ‘REGUPOL sound and drain 22’ is 15mm thick and has a load bearing capacity up to 50 kN/m².

It has also been used in schemes such as: The Marienturm in Frankfurt am Main – a 38-storey building primarily occupied by offices; Ikea West Station in Vienna; the Lindley Lindenberg – a boutique hotel in Frankfurt; and the Volkstheater in Munich.
