Selectaglaze recently provided a secondary glazing solution for the Stansted Airport College, part of Harlow College.
Stansted Airport College is the first on-site education facility of its kind at any major UK airport, designed by Pascall+Watson and built by Willmott Dixon.
With just one runway serving all take off and landings at London Stansted Airport, and the college’s location not far from the end of it, noise was a big worry for those using the facility. Acoustic consultant Cole Jarman Associates was employed to make recommendations, to create a quiet and comfortable learning environment.
As it was a new build, high-performance primary double glazing was installed, but it was not enough to meet the acoustic requirements. This is where Selectaglaze came in.
Selectaglaze provided a solution with secondary glazing. It is the most successful technique of acoustic insulation for windows in extremely noisy areas. Although commonly used in Listed buildings, they can also provide much needed additional performance for new builds in areas of high traffic or near major transportation hubs.
Acoustic tests have revealed that Selectaglaze secondary glazing can provide a 45dB reduction if set 200mm from a single glazed primary window with 6mm glass. Based on this, if used in combination with high-performance primary windows, then the dB rating requirements would be met.
Selectaglaze proceeded to install 32 units across the site with their Series 10 – 2 and 3 pane horizontal sliders and a Series 41 casement door. All were installed with a cavity of 200mm and tightly sealed.
Karen Spencer, Principal of Stansted Airport College, explains: “It is an amazing place to work, with state-of-the-art facilities for the students. Every day they have a clear line of sight to the workplace – a real incentive for completing their courses and going on to careers at London Stansted airport. As for the building, it is hard to believe that we are at the end of the runway, as it is so quiet inside the building. Often, the only giveaway that an aircraft is taking off is the amazing panoramic view out of the windows.”
Not only have the staff and students already seen the massive acoustic benefit of the secondary glazing, but they should also gain from thermal insulation it provides and the added security.
