low reflectivity glass, an adapted solution to enable easy window opening
Commissioned by King Charles II in 1682 and designed by Sir Christopher Wren, the Royal Hospital Chelsea is of significant historical importance. Home of famous retirees, the Chelsea Pensioners, the institution offers essential care, camaraderie and support to retired British Army veterans.
As part of extensive sensitive renovations to the building, its overall energy efficiency needed to be improved. The project aimed to make rooms warmer and more comfortable for residents whilst driving down energy costs and maintaining the overall aesthetic of the building.
The ‘Long Wards’, housing the pensioners’ bedrooms, are consistently occupied, and so keeping disruption to a minimum was a priority.
Working with architects, Peregrine Bryant, we made several adaptations to our original design to ensure our glazing system perfectly fit the brief.
Using non-reflective glass, the new design features improved ventilation and enables the windows to be fully opened. The system is spring-adapted, making it balanced and easy to control.
