Overlooking London's Regent's Park, this historic terrace of magnificent Grade I Listed Regency properties - formerly the headquarters of British Land - has been fully restored and converted back for residential use. These five storey properties with their enormous entrance halls beautifully finished with near-white limestone flooring and grand staircases sweeping through the buildings make a spectacular first impression. The main reception rooms are of classic dimensions with floor-to-ceiling windows allowing natural light to stream into every corner of the room. The traditional single glazed sash windows are a defining feature of the terrace but do not provide the levels of comfort and thermal performance that is expected today. Selectaglaze was tasked with the design and installation of secondary glazing for sash windows to markedly reduce heat loss, remove the discomfort of draughts and provide significant noise insulation. In addition, Selectaglaze has particular expertise in working with heritage windows glazed with Crown Glass. The requirement for improved security to selected windows was met with products meeting the standard for 'Police Preferred Specification'.
