Roofing Updates
SOUND AND DRAINAGE PROTECTION
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.
CMS Danskin Acoustics’ Ian Bull said: “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.”
‘REGUPOL sound and drain 22’ provides highimpact
sound insulation levels of 28 to 37dB
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.

WHITESALES NAVIGATES HERITAGE CHALLENGES
Whitesales has replaced the original timber rooflights in the Grade II* listed Birmingham Museum & Art
Gallery with new bespoke aluminium rooflights, ready for the reopening of the museum during 2024.
Built in 1885, the Birmingham Museum & Art Gallery has long housed treasures from the likes of Edward Burne-
Jones, William Morris and Dante Gabriel Rossetti, and has an unrivalled 2,000 piece Pre-Raphaelite collection.
However, it closed in November 2022 for essential maintenance which has included electrical work, upgrading of
the heating, lift replacement and roof repairs. The new rooflights were a key element in the roof repairs, so the
challenge for Whitesales was to supply and install high performance, energy efficient replacements for the timber originals, which satisfied the
constraints of the Grade II* listing and met the requirements of the City Council’s conservation office. The solution they developed included one bespoke
Whitesales Monopitch 2610mm x 1260mm rooflight with vertical front face and sides set at 350mm, and two bespoke lantern rooflights with sides set at
440mm and 450mm, all finished in an anthracite grey on the exterior and white on the interior, and all CWCT TN92 Class 2 non-fragile to ensure the
safety of anyone walking on the roof. Whitesales worked closely with contractors ISG throughout the design and specification process. They visited the
site for a survey, attended design meetings and delivered a sample to the site so that everyone on the client team was happy with what was being
supplied in terms of both performance and aesthetics. They also ensured that the rooflights were all fabricated and safely delivered to site in
manageable-sized elements to take into account the fact that access in and around the city centre site was difficult. Whitesales has a long standing
relationship with ISG, based on the quality of the work carried out on previous projects. For ISG’s Trainee Construction Manager Ryan Linnecor,
Whitesales impressed with their knowledge and experience on heritage schemes. He commented: “Whitesales had a clear understanding of the Grade
II* listed scheme and the constraints that presented. They impressed us once again with their approach on how to undertake the work sympathetically
and the finished installation is of a very high quality.” www.whitesales.co.uk
