CMS Danskin Acoustics has a new sound reducing underlayment product specially developed for external surfaces, such as on rooftops, terraces and balconies, which also provides rainwater drainage and membrane protection.

‘REGUPOL sound and drain 22’, exclusively available from CMS Danskin Acoustics in the UK, is a polyurethane elastomer composite with a dimpled profile on the underside to facilitate drainage and a geotextile-laminated top to prevent dirt penetration.  It provides impact sound insulation with effective acoustic results in a range of different structures.

“Sound insulation on roof terraces is just as important as indoor sound insulation because structure-borne sound from footfall or services plant, such as rooftop air conditioning units and heat pumps, is transmitted from the external surface to the building interior.  However, most sound impact materials are unsuitable for outside applications.  REGUPOL sound and drain has been developed for outdoor use.” said CMS Danskin Acoustics’ Ian Bull.

‘REGUPOL sound and drain 22’, provides high impact sound insulation levels of 28 to 37 dB depending on the specific build-up, is rot-proof, largely resistant to ageing, gives good drainage and water flow capacity and functions as a protective layer.

Acoustic test data is available for six floor assemblies, including varying thicknesses of concrete tiles, wooden decking boards and ceramic tiles, as well as test data confirming compressibility, fire, thermal and moisture behaviour and resistance to ageing.

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

Projects to date include The Marienturm in Frankfurt am Main, a 38-storey building primarily occupied by offices, and 36-38 Berkeley Square, a new office and retail development in London’s Mayfair.

‘REGUPOL sound and drain 22’ is a Bronze level Cradle to Cradle Certified® product.  Cradle to Cradle is a multi-attribute standard for designing and making products that enable a healthy, equitable and sustainable future.  Cradle to Cradle Certified® is a registered trademark of the Cradle to Cradle Products Innovation Institute.

Distributed in the UK by CMS Danskin Acoustics, REGUPOL products are specified worldwide for their noise and vibration reduction properties.

Part of SIG plc, CMS Danskin Acoustics produces and sources insulation products advising on all matters relating to sound proofing materials and noise reduction strategies, including floors, ceilings and walls, to combat airborne and impact noise.  Notable projects include the Bank of England, the Royal Shakespeare Theatre and The Shard.
