Selectaglaze takes on a Titan

“Atlas House”, 1 King Street is an impressive Grade II Listed building located on the corner of Cheapside and King Street in the heart of the City of London.

The building partly dates back to 1842 but has undergone a number of additions and renovations. TateHindle has designed the latest refurbishment, bringing the building up to the highest modern standards for office use.

The building has a classic façade with traditional sash windows, an important and attractive feature that could not be changed. However the original windows are thermally inefficient, draughty and incapable of dealing with the high noise levels, so not suited to present day needs. The solution was to install secondary glazing. An independent internal window frame set with a cavity of 100mm ensures that the two glass panes are acoustically decoupled, generally reducing noise levels by 45dB. The frame also traps an insulating layer of air between the windows and, together with efficient seals that minimise air leakage, markedly reduces heat loss.

TateHindle approached Selectaglaze, the UK’s leading designer of secondary glazing systems for advice and assistance as the latter has considerable experience of working within Listed buildings and has full laboratory test reports for noise attenuation capabilities. The solution was a hinged casement set with a cavity of 150mm. Twin compression seals minimise acoustic loss and colour matched flush hinges and flush locks ensure that the windows are discrete and unobtrusive. Full sized hinged casements were used wherever possible but in locations with lowered ceilings a high level fixed panel was introduced to allow the casement to clear. A total of 165 windows were treated.

Founded in 1966, Royal Warrant holder Selectaglaze is a specialist in the application of secondary glazing within buildings of all styles.
