5-6 Connaught Place has been beautifully transformed, into exclusive luxurious apartments. The renovation of these Grade II Listed properties has won the accolade of best residential renovation in the UK 2014-2015. Selectaglaze was approached by John Sisk & Sons ltd for advice on how to reduce noise ingress and heat loss from the large Georgian style sash windows which form such an important architectural feature of the building. To demonstrate the unobtrusive nature of Selectaglaze secondary glazing a sample unit was initially installed. The sound reduction and aesthetic qualities of this unit were such that secondary glazing was applied to the rest of the building. A total of 69 secondary units were installed using five different styles including curved units. Toughened safety glass was used to glaze all the secondary glazing units. A peaceful, warm environment has been achieved whilst retaining the aesthetic integrity of the original primary.
