city regeneration delivers tranquility


A new lease of life is being given to an iconic tower block in Liverpool city centre.

Marwood Tower has been redeveloped by Liverpool Mutual Homes  in partnership with principal contractor Willmott Dixon Housing, and John McCall Architects. The existing tower block was refurbished, and a single storey extension built, to provide 81 apartments for the over 55s, complete with courtyard garden, bowling green and outdoor gym.

The £9.5m development- in Gt Homer St- one of the city’s main arterial routes- forms part of the £150m Project Jennifer regeneration scheme. A key element of the build is the roof, executed by Churchmore. The advanced roofing technology specialist stripped the existing asphalt roof, and replaced it with a new vapour control layer, insulation, and mechanically fixed 350m2 Protan SE1.2mm standard overlap dark grey single ply to the concrete slap.

Willmott Dixon project surveyor Dave Dobson observed, “Protan membrane gives us the product we wanted with the quality guarantee we required. Also, it offers a lightweight and efficient construction technique, which lent itself well to the constraints of operating on the roof of a 15 storey tower. The flexibility of Protan’s membrane also allowed for the weathering details to tie in nicely with the cladding.”

Churchmore managing director Andy Monk added, “We chose Protan because it is a good product, easy to use, and we get excellent service: we can source not just the single ply membrane but the VCL and insulation from Protan, which further facilitates project efficiency.”

Protan SE, available in 1.2mm, 1.6mm and 1.8mm, is developed to cope with even the most extreme weather conditions without detriment: it is certified to ≤ -30°. Hot-air welded at joints and mechanically fixed to the roof, the membrane achieves durability in excess of 30 years, with air leakage controlled/minimised in line with latest Building Regulations.

Protan SE membrane is also certified to deliver, and potentially surpass, the energy efficiency requirements laid down in Approved Document L, and, under the Green Guide, achieve a A+ rating. The single ply membrane is just part of Protan’s comprehensive, quality offering, which includes green and protected roofing solutions.

Established some 75 years ago, and still privately-owned, Protan is one of the top 3 membrane manufacturers in Europe. A full support service, from NBS specification and in-house CAD design through to technical advice is provided from Protan UK’s Warrington office.
