CoSH Level 4 development
Composite Curtain Walling & 70mm Window Systems, New Build, Manchester
A Code for Sustainable Homes Level 4 development in Gorton, Manchester features more than 800 windows in REHAU’s TOTAL70 PVC-U system and 20 screens in the REHAU Polytec 50 aluminium clad curtain walling system.
80 houses and 124 apartments have been built on four sites in the suburb of Gorton in the first major development of new council housing by the City of Manchester Council for more than 30 years.
The focus throughout is on sustainability, security and lifecycle costs and the REHAU systems satisfied all three criteria with a WER ‘C’ rating on the windows, a Uf-value as low as 0.88 W/m2K on the curtain walling, Secured by Design accreditation and proven low maintenance and long term performance.
All of the frames were coloured grey on the exterior using REHAU’s Acryl II PVC-U colouring system and the windows are white on the interior to give tenants greater flexibility in terms of decoration.
The screens, up to 4m high, were used in the stairwells of the four storey apartment blocks and were preferred to aluminium screens because of their better thermal performance and ease of fabrication.
The development was designed by architects Bowker Sadler and is now managed by Guinness Northern Counties.
