Caledonian Road, WhatHouse? Gold prize winner - acoustic secondary glazing


Project Profile


retrofitting, sustainability

Selectaglaze bespoke secondary glazing played a vital role in the retrofit of this prize winning project. Igloo, specialists in sustainable developments acquired a plot in Caledonian Road back in 2012, which was in a poor state of repair. Situated virtually under an overground line, the property suffered from poor acoustic insulation. However Igloo saw potential in this Victorian townhouse with its courtyard and adjoining stable block. Their plan was to convert this single dwelling and its outhouses into 25 apartments and 3 commercial studios. Caledonian road content All planning requirements had to be adhered to correctly as the property is within a conservation area. In order to achieve this, care was taken to preserve the original Victorian façade and key historic features. Particular attention had to be given to the original sash windows. These windows with their ageing single glazing and weathered timbers were in need of urgent restoration. From the outset of the project acoustic secondary glazing was specified, which can achieve sound ingress by 45dB. John Sisk, Igloo’s main contractor knew that Selectaglaze’s bespoke acoustic solution would meet the requirements of the project. Each window opening is treated individually, as no two window openings are ever the same, particularly in older properties. Tailored acoustic units allow for optimal installation which in turn ensures that the project meets its acoustic reduction targets. Selectaglaze is also highly experienced in sympathetically treating older buildings. Six Series 20 vertical sash units glazed with 6.8mm Stadip Silence glass were manufactured and installed. With their slimline frame, these units provide a discreet solution ideal for heritage projects. The Series 20 range is robust enough to comfortably hold the thicker glass required for most acoustic treatments. Each unit was positioned at a minimum of 100mm from its primary to ensure maximum noise reduction. “We chose Selectaglaze over other secondary glazing companies because of the knowledge and technical advice they provide. The assistance we have continually received from Selectaglaze has been outstanding. Throughout the whole process, even at tender stage, Selectaglaze has been great to work with.”  Jonathan Lisseter Design manager at John Sisk. As testament to the quality of this project, Igloo was awarded GOLD for the best sustainable development at ‘Whathouse? Awards 2015’.
