This year marks the 50th birthday of Selectaglaze; who designs, manufactures and installs bespoke high-end secondary glazing for projects of all types requiring noise and thermal improvements, as well as enhanced security. For many years there has been a misconception around the aesthetics of secondary glazing; however it has evolved significantly and is now being incorporated into renovation projects more and more.
When dealing with Listed buildings or those in conservation areas which have original draughty windows that can’t be removed, the only way to make improvements would be to install an unobtrusive slimline secondary glazing system, which follows the sight lines of the primary window, making it hard to notice from the exterior of the building and is a reversible adaptation. Selectaglaze secondary glazing can achieve U-values of around 1.9 and has been included in various projects which have achieved BREEAM or EcoHomes ratings.
Along with enhancing the U-values and in turn contributing to a reduction in energy costs, secondary glazing is also the most effective method of noise insulation. A reduction of 45dB can be gained in combination with the primary window if a gap of 100mm or more can be made.
Selectaglaze has a range of in-house designed systems, which have been carefully engineered to ensure they are sympathetic to not only the original windows, but the rooms in which they feature. The frames can be colour matched to further blend in with the surrounds. Some of the systems will still allow for the use of original shutters, found in a number of Listed buildings.
Some of the most recent projects Selectaglaze has been used in are:
- Grade II Listed Connaught Place has recently had a make-over and been transformed into exclusive luxurious apartments. Secondary glazing was used to provide enhanced thermal performance to the original windows as well as provide added security.
- Ham Yard Hotel, London is a new build hotel that despite having brand new double glazing, still suffered high noise levels from the busy streets outside. Hoteliers livelihood is dependent on the guests having a peaceful and good night’s sleep, so they sought the help of Selectaglaze to create a solution with their secondary glazing. Large sliding units with acoustic glass were colour matched and installed into the hotel façade suffering from noise ingress.
- Nestling in the shadows cast by St Pauls Cathedral, is Grade II Listed Chapter House. Built between 1712 and 1714, it is now the administrative heart of the Cathedral. It has recently been restored and had its insulation upgraded, with secondary glazing installed into grand oak panelled rooms, as well as stair wells, which have helped bring the offices up to 21st century standards.
Selectaglaze has a wealth of experience working with architects and interior designers to help maximise the benefits that can be achieved with secondary glazing on their projects. A free technical service is offered as well as RIBA approved CPDs about the technicalities of secondary glazing and how it can provide window security.
