Science Flagship ‘Pro-tected’ With State-of-the-Art Roofing Technology

A flagship innovation facility which will enable energy research and development is using advanced ‘green’ technology in its building.

Willmott Dixon has refurbished the existing building on the University of Chester’s Thornton Science Park to create a new, multi-million-pound Intelligent Energy System Demonstrator (IESD).

The project includes upgrading the five-storey building’s roof. Sub-contractor Range Roofing has used Protan single ply polymer membrane, secured using a combination of traditional mechanical fix systems and the innovative SFS intec isoweld® 3000 system. In total, Range used 1200m2 of Protan SE1.6mm, supplied in 2m wide rolls.

Range Roofing’s Nick Haves explained: “The main plan area is timber, so we could use traditional mechanical fixing techniques; the other element is a concrete slab overlaid with infill material, plus over the years there have been several lots of repairs undertaken.

“As a result the thickness varies massively across the roof, up to 500mm in places! It also had a variety of fall across its span, and screed. We therefore needed a method that delivered optimum adjustability, hence our choice of isoweld®.”

Wider material

He added: “Protan’s ability to provide wider material was a big benefit too, giving us greater flexibility in our positioning of the fixings, not necessarily at close centres, yet still ensuring the roof would perform. It also offers environmental benefits, which complemented the end use of the building.”

Due for completion in spring 2017, the IESD will deliver a space where industry can work alongside the University of Chester’s Faculty of Science and Engineering to new power saving and distribution technologies for low cost, environmentally responsible energy sources.

It is being funded through the Growth Deal awarded to Cheshire and Warrington Local Enterprise Partnership (CWLEP). Philip Cox, Chief Executive of CWLEP, said: “The IESD is a nationally significant project that will be a flagship for the site.”

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.

It has been proven to perform with the SFS intec isoweld® 3000 field fastening system solution for flat roofs. Isoweld® works with induction technology and is non-penetrating. Secure attachment is achieved through the welding of the membrane to a dedicated stress plate, independent of the membrane overlaps.

Protan SE membrane is under the Green Guide, accredited with achieving a A+ rating. The single ply membrane is just part of Protan’s comprehensive quality offering, which includes green and protected roofing solutions, all fully BBA certified.

Established some 75 years ago, and still privately-owned, Protan is one of the top three membrane manufacturers in Europe. A manufacturing member of SPRA, Protan can provide a full support service, from a comprehensive RIBA-approved CPD programme in single ply membranes, NBS specification and in-house CAD design through to technical advice from Protan UK’s Warrington office and training facility.
