The home of the Institution of Civil Engineers recently underwent repairs and renovation works with a particular requirement to ensure the Great Hall became a warmer and quieter space for events. A total of 22 units were installed to treat seven large openings; the original iron windows had narrow sightlines so it was important that the secondary glazing reflected this whilst still retaining functionality and access for ventilation, cleaning and maintenance. The largest of these openings also featured a full roman curved head and stood in at nearly 7m tall and 2.5m wide. The installation was carried out to meet a specific programme date, so Selectaglaze worked closely with clients to ensure the deadline was met. “Selectaglaze came highly recommended and the service and end-product we received at One Great George Street exceeded our expectations. Our historic Great Hall now benefits from discreet secondary windows which minimise noise and provide insulation to the room - all complete on budget and to programme. I wouldn’t hesitate to recommend the company to others" Phil Ackers, Head of Building Services, One Great George Street
