PVC plays key role in biodiversity

protan greenwich retail emailThe final section of Greenwich Shopping Park has now been handed over, with the construction of five units that will be home to, among other household brands, Matalan, Starbucks, Frankie & Benny’s. Designed by Ratcliffe Groves Partnership (RGP) and built by Cardy Construction, the units feature Protan PVC membrane on the roofs.

Roofing contractor RKC Roofing adhered just under 600m² of 1.5mm Protan EX-A fleece laminated membrane to each of the exposed roofs of units A-D. A similar quantity of Protan Bio-Diverse G membrane, also 1.5mm thick, was used on the two-storey Unit E, a ‘high profile’ corner unit containing Frankie & Benny’s on the ground floor and the site security suite and management offices above.

Nick Ratcliffe, director of RGP, explained: “It was a brownfield site that, having been unoccupied for years, had become a habitat for plants and wildlife. The aim with the bio diverse roof was to recreate that environment at high level, to replace the habitat. It also formed part of our environmental credentials for BREAAM.”

RKC’s Lee Jones added: “A green roof was specified, so we suggested Protan as the solution. As we were using Protan for the adhered roofs, it offered all involved a best value solution to use the same source for all the roofing membrane.”

Protan says its EX-A membrane has a proven durability of 30+ years, is quick to install and is developed to cope with even the most extreme weather conditions without detriment: it is certified to ≤ -30°.

Protan G membrane is a glass fibre reinforced, microbe durable PVC membrane for gravel ballasted roofs, inverted roofs, and green roofs. It can withstand high and low temperatures and attack by micro-organisms. Loose-laid, it provides a fast and safe means of creating an FLL compliant roof.

Protan membranes achieve durability in excess of 30 years, with air leakage controlled in line with latest Building Regulations, and are fully BBA certified.
