Fully funded flat roof solutions for Airedale Academy


roofs, which had surpassed their natural life expectancy and were experiencing water ingress. Prior to the work commencing on site, flat roof manufacturer Bauder helped the academy successfully secure £1.5 million of funding for the required works by assisting them with all stages of the application process. All of the original waterproofing on the

school’s campus was then removed before being replaced with over 7,200m2


of Bauder’s


premium reinforced bitumen system, Bauder Total Roof System, by approved contractor FRS Roofing Services. The system build-up included Bauder’s PIR Insulation for superior thermal performance and tapered insulation to effectively create drainage falls without having to incorporate them into the structure. As part of the necessary works, 20 new Bauder rooflights were also expertly


iredale Academy in Castleford recently underwent significant refurbishment to repair its failing flat


fitted to give essential daylight to the building’s interior. A challenging element of this installation


was the number of intricate detailing requirements, with the roof possessing over 20 separate roof areas, calling for exceptional levels of workmanship from FRS. There were also some health and safety implications, with asbestos having been found within the building structure. Consequently, specialists were called in to ensure safe removal and some roof areas were overlaid to minimise the


possibility of any asbestos debris being dislodged and therefore contaminating the rooms and corridors below. The academy remained open and fully operational throughout the works, which caused logistical challenges, however all deliveries were timed as not to conflict with vehicles moving in and out of the facility and the team worked closely with the client to agree working hours to reduce disruption to the students and staff. Mike Leake, Vice Principal at Airedale


Academy: “The expert support we received from Bauder was crucial in helping us secure the necessary funding and the final outcome of the roof refurbishment is outstanding. We are already starting to notice the benefits, including cost savings as a result of the insulation upgrades, and our long guarantee gives us total confidence about the future performance of our roofs.”

in Austria, defined by perforated Nordic Brass copper alloy from Aurubis, takes a particularly bold approach. The 5.5km long Bosruck Tunnel passes


Bold brass R


through the Ennstal Alps, connecting Upper Austria with Styria. The original, two-way traffic tunnel has been renovated and a second, new tunnel built alongside. Now part of the A9 Pyhrn motorway, it is used by around 18,000 vehicles each day. This impressive engineering feat is announced by new portal structures at both ends of the tunnel. The highly architectonic approach taken is


unusual for projects of this kind, suggesting a new building typology celebrating transport infrastructure. A series of screens – made up of perforated Nordic Brass cassettes, profiled and arranged to reflect the verticality of the surroundings – partially conceal buildings and equipment essential to the tunnel’s operation and safety. The rhythms of the screens highlight the experience of travellers


oad and rail tunnels are not often associated with inspirational design but this tunnel portal building


as they approach and drive straight through the building, via the dramatic ‘flying roof’ entrance and exit galleries, acting as transition spaces between inside and out. Nordic Brass was chosen for its long-life


and durability, including resistance to road salt, following trials simulating the exposure of the material over 30 years. Along with three other Aurubis copper or copper alloy clad projects, Bosruck Tunnel has been shortlisted for the 2017 European Copper in


Architecture Awards. All four shortlisted projects will also be featured on the Aurubis stand at the ‘100% Design’ event in London Olympia, 20-23 September. Nordic Brass – also available with a pre-weathered finish – is produced by Aurubis, part of the world’s leading integrated copper group and largest copper recycler. Other copper alloys include Nordic Bronze and the innovative Nordic Royal, an alloy of copper with aluminium and zinc, giving it a rich golden through-colour and making it very stable. The Aurubis architectural range also includes Nordic Standard ‘mill finish’ and Nordic Brown pre-oxidised copper, offering lighter or darker shades of brown determined by the thickness of the oxide layer. Various Nordic Green, Nordic Blue and Nordic Turquoise factory-applied patinas have also been developed with properties and colours based on the same brochantite mineralogy found in natural patinas all over the world.
