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

Unique design wins prestigious roofing award

Brighton’s Metropole Hotel was the venue for the NFRC’s prestigious annual awards event. Single ply membrane manufacturer Renolit alongside Ilkeston based contractor, Advanced Roof & Wall, were voted outright winners in the Flat Roofing / Single Ply category for the technical competence jointly contributed to the the £21m Pods and Central Park funded by North Lincolnshire Council, Yorkshire Forward and Sport England.

The irony of  the category was not lost on TV personality Penny Smith who presented the Renolit and Advanced team with their award, noting that this unique five domed design is anything but flat; comprising of five pods finished in a range of materials, collectively contributing to the development’s remit to blend into the park landscape.

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 adventurous and innovative use of single ply membrane ever seen in the UK.

Renolit’s ALKORPLAN membrane was chosen for its light and versatile properties, ease of installation and enviable reputation for reliability; the  system is arguably mainland Europe’s most specified single ply waterproofing membrane.

The individual pod diameters extend from 20 up to 50 metres, with the largest covering an area close to 2000 square metres. The Renolit ALKORPLAN system has been deployed as a waterproof foundation beneath two cedar shingle covered domes, one sedum green roofed dome and an aluminium cladded dome. On the final dome, it has also been utilised in its own right combining with Renolit’s ALKORDESIGN profile to create an attractive geometric pattern.

Paul Young, Director S&P Architects said

“We called Renolit to review our options on waterproof coverings, they were able to provide solutions that would complement the innovative design. Understanding the sensitivity of the detailing to achieve the ‘skin’ was paramount to our requirements. This was achieved using a combination of their membranes. The result is a stunning building that is unique to this type of building. S&P are delighted that the result achieved the intent of Andrew Wrights competition winning design.”
