At 160m (525ft) tall, London??s distinctive Walkie Talkie building required an exceptional roofing solution. Fenland Roofing and Sika Sarnafil single ply were up to the challenge. Awarded the project in February 2014, Cambridge-based contractor Fenland Flat Roofing was required to provide a lightweight walkable roof area for the access walkways and perimeter edges of the glazed roof to the garden and restaurant. Sarnafil G410-12EL single ply provided the perfect solution to this design criteria thanks to its excellent flexibility and weldabilty, while offering outstanding resistance to weathering, including permanent UV irradiation. This was installed in Lead Grey to the BMU Track and covered with SarnaTred walkway tiles, allowing durable and slip resistant access for maintenance workers ?? a vital safety consideration. The second part of the project was to provide a flexible high performance waterproofing membrane to the bespoke Shoulder areas in white, to match in with the steelwork structure colour. Again, Sarnafil had the product to suit the application, Sarnafil G410-15EL Traffic White.
