Look again...this is single ply membrane at its innovative best

Funded by North Lincolnshire Council, Yorkshire Forward and Sport England the £21m Pods and Central Park project will become a sporting centre of excellence; a hub that will function not only as a leisure facility for the whole community surrounding Scunthorpe, but will also deliver sports education and leadership training.

The unique five domed design comprises of pods finished in a range of materials, each contributing to the development’s remit to blend into the park landscape. Renolit’s involvement, alongside Ilkeston based contractor, Advanced Roof & Wall, has been short-listed for the prestigious NFRC roofing awards, 2011.

Each dome is waterproofed using the RENOLIT ALKORPLAN system and whilst the complex is thought to be the UK’s largest timber-built geodesic project, it also demonstrates possibly the most innovative use of single ply membrane ever seen in the UK.

RENOLIT ALKORPLAN provides a sleek, incredibly versatile and highly creative roofing system. That’s why it is arguably mainland Europe’s most specified single ply waterproofing membrane at between 20 to 40% the weight of many traditional multilayer systems …and developed for easy installation.

The individual pod diameters extend from 20 metres up to nearly 50 metres, with the largest covering an area close to 2000 square metres. Not only is the RENOLIT ALKORPLAN system deployed as a waterproof foundation beneath two cedar shingle covered domes, one sedum green roofed dome and an aluminium sheeted roofed dome… it has been combined with RENOLIT’S ALKORDESIGN profile to create a geometric pattern, similar in appearance to a standing seam roof.

Each of the pods specifications set a separate challenge and how the RENOLIT technical team responded to prove the versatility and durability of the RENOLIT ALKORPLAN range…  single ply roofing membrane at its technical and creative best.
