The central chapel of this Grade II Listed impressive Georgian style building, has now been converted to the reception for the Early Years Centre. However in spring 2015 the Northern line extension works are to begin in earnest, which will disrupt the environment of the nursery until at least 2020 when it is due to open. The current single glazed windows offer minimal acoustic protection and any ill-fitting frames also allow dirt and dust into the building.  Selectaglaze was tasked with providing a solution using its bespoke secondary glazing systems as a result of similar works completed on the Crossrail scheme. A fully independent tailor made window system set 100mm or more from the existing window achieves a noise reduction of 43-45dB and high performance frame seals both limit airborne sound and trap the dirt and dust. With the property being Grade II Listed, secondary glazing is a great solution as it is a reversible adaptation. Selectaglaze produced sympathetic designs for Listed building consent using sliding and fixed systems with locks to ensure permanent protection.
