Green roofing supports impressive BREEAM Excellent project

Icopal’s technically advanced, green biodiverse roofing and living walls have been installed to support the BREEAM Excellent rating and create a pleasant outdoor space for occupants at 20 Bentnick Street, a premium mixed use development just off Marylebone High Street in a conservation area in the heart of London.

The original building, in need of a complete refurbishment, was subject to a £15m design and build project. In keeping with its Georgian beginnings, the building’s original Grade II listed façade was retained with the construction of a new five-storey building plus basement creating 40,000 sq ft of premium offices and three luxury penthouse apartments totalling 4,300 sq ft.

Achieving BREEAM Excellent status was one of the primary objectives for this project. One contributory factor to realising this was the specification of a green roof and living wall solution.

London-based roofing specialist, McCormick Flat Roofing Ltd specified the Icopal roofing solution.

Icopal’s innovative range of high performance green roofing systems, with its wide product portfolio, offered flexibility of design with guaranteed quality and long-term durability.

Installed to the first and fourth floor roof deck areas, the Icopal green roof system comprises a series of components including Icopal’s Sureplan FPO single ply roofing membrane bonded on Thermazone insulation, a highly efficient PIR rigid insulation that is manufactured without the use of CFCs/HCFCs and has zero Ozone Depletion Potential (ODP). This is laid over Icopal’s Monarflex vapour control layer and finished with Icopal’s green biodiverse roofing and living wall feature.

Stewart McCormick, McCormick Flat Roofing Ltd’s managing director, said: “We worked closely with Icopal’s technical advisors to ensure the specification was exactly fit for purpose. The team’s experience in waterproofing technology allowed us to deliver the correct specification of roof membrane and green roof system to suit the criteria for the Bentnick Street project, based on the choice of landscaping, performance and robustness required.

“It was great that this project was recognised recently when we were named as award winner in the ‘Green Roofing’ category at The Intelligent Membrane Association (IMA) Contractor Awards 2015. Green roofing installations are certainly a popular option for BREEAM related projects.”
