Built on the site of the former Lewisham Bridge Primary School, Prendergast Vale College opened for the start of the 2012/13 academic year. The original building which received Grade II Listing "as an outstanding example of Edwardian school architecture", with English Heritage, has been carefully incorporated into the overall design. The building needed sympathetic refurbishment and adaptation for the present day and the imposing single glazed windows presented a significant challenge for the College's energy efficiency targets. Low emissivity glass was recommended as it can reduce heat loss through traditional windows by up to 60%. High performance seals were also recommended in order to markedly reduce draughts. Selectaglaze installed nearly 200 secondary windows, mostly vertical sash, some with arched heads. All were finished in white powder paint. An added bonus from the installation of secondary windows is the high levels of noise insulation, typically 40-45dB. The large airy rooms now provide a comfortable, draught-free, quiet environment, conducive to learning. Since this project was completed the Series 30 has been superceeded by the Series 31 lift-out.
