The Grade II Listed Supreme Court is a neo Gothic building designed by the renowned architect James Gibson (1864 – 1951). Originally built to house the offices of Middlesex County Council, it now is home to the Supreme Court. In order to provide the necessary facilities the building underwent extensive improvements and adaptations in 2009.   As part of this work Selectaglaze were asked to provide a secondary glazing solution for the existing windows. The original windows offered little to no protection from noise ingress which had become an increasing issue over the decades. The Supreme Court forms the western end of Parliament square which, as with much of London, suffers from heavy London traffic 24/7. By its nature secondary glazing is decoupled from the primary window. This feature, together with an airgap can result in a treatment that reduces noise by in excess of 45dB.  The Supreme Court corridor image Secondary glazing corridor solution Due to the sensitive nature of work taking place within its walls it was decided that the building also required additional levels of security. As with many traditionally built buildings The Supreme Court boasts an array or beautiful single glazed windows. Series 55 Security DFL together with Series 50 Security HC where use to treat a range of different window shapes and styles to ensure the building attained its required security levels. Selectaglaze where consulted during the initial planning of the adaptation to come up with a solution to a design problem. In order to create a safe quiet court space the improvements required the sectioning off of a gallery that run the whole length of the proposed new courtroom. Selectaglaze were able to design a screen solution whereby this modification could be made without compromising the amount of natural light and feeling of space within the building. As part of the EU’s energy performance of buildings directive the project also aimed to improve the energy efficiency of the building and achieve a BREEAM ‘Very Good’ rating. Acoustic security glazing gives a window the additional benefit of a marked increase in thermal integrity. Successful secondary glazing treatments can give a result in U-values below 2.0.
