Selectaglaze has installed secondary glazing to a Grade II listed building in the heart of London’s West End.

The renovation and conversion of 5-6 Connaught Place from its post Second World War use as office space to luxury homes was undertaken by Redrow London. Main contractor John Sisk & Sons turned to Selectaglaze for the most effective way to reduce external noise levels.

Secondary glazing from Selectaglaze was fitted to the room side of the existing primary windows. With a gap of at least 100mm between the primary and secondary glazing, 45dB is achievable. Along with noise reduction, secondary glazing helps to eradicate draughts by trapping them in an insulating layer and reduces heat loss, helping to create a more comfortable living space.

A total of 69 toughened safety glass units were installed in five different styles, including curved units to mirror the styles of the primary windows.
