Situated in Mayfair, 10 Cork Street is in one of London’s most sought after areas; built in 1924-1925 to a design by John Belcher and J.J Joass. Pollen House is a striking stone clad building with a distinctive blueprint. Sitting close to the Royal Academy and surrounded by the likes of Burlington Arcade and other high-end retail establishments, who wouldn’t want to work in this vibrant area in offices that have had a 21st century internal make-over? A high specification design by Ben Adams Architects has created a very attractive environment but one that needed significant attention to the existing steel windows in order to minimise the problem of traffic noise. Selectaglaze with its considerable experience in acoustics was approached for advice. Noise reduction of about 45dB has been achieved through treating each window with a single hinged casement glazed with 6.8mm acoustic laminated glass. The minimal frames with flush hinges and locks provide clean lines which complement the existing windows and the new interiors. An additional benefit of the secondary glazing is an approximate halving of heat loss and near elimination of draughts that ensures a more comfortable working environment.
