A Kalzip roofing system from Corus Building Systems provides a striking barrel-vaulted roof for a new £60 million waste and recycling centre in north London. Part of Arsenal Football Club's £357 million Emirates Stadium project, the centre will act as a waste-transfer site for Islington and surrounding councils.
A combination of 10,000m 2 of Kalzip standing-seam roofing, 1,000m 2 of Kalzip Nature Roof, a Kalzip fall-arrest system and Kalzip fabrications, ensures the high-performance roof meets strict planning and environmental criteria.
The rolled roofing curves dramatically through a radius of 4m and extends down the northern elevation of the main building.
The entire system has been tested rigorously to ensure it achieves high acoustic specification, says Corus, and is then re-engineered to reduce the overall cost without compromising the essential integrity of the roof construction. The final specification incorporates a 1.2mm steel liner, a 1mm Kalzip 50/429 profiled external sheet and 280mm of insulation, compressed to 245mm.
The planning submission for the relocated waste-treatment works included a detailed environmental-impact assessment and stipulated the use of a green roof system on part of the scheme. The Kalzip Nature Roof on the building's office block comprises a Kalzip aluminium roofing system combined with Nature Mat, an instant, self-sustaining plant covering.
The treatment works' roofing system was installed by Teamkalapproved contractor Kelsey Roofing Industries, with Kalzip's horticultural partner Blackdown Horticultural Consultants managing the planting of the Nature Roof.
