As a staple of London’s architecture throughout the Georgian Period (1714-1837), the Victorian Period (1837-1901) and the Edwardian Period (1901-1910), traditional sash windows can still be found on almost every street in the city. Sash windows comprise of two glazed sashes housed within a timber box frame. These sashes are counterbalanced by heavy lead weights concealed within the frame, and the lead weights are connected to the sashes by a cotton sash cord that runs over a pulley at the top of the frame.

Core Sash Windows’ double glazed Sash Windows are specially designed to closely match the designs most famously associated with each of the Periods in which the Sash Window was fashionable. This is achieved through our pain-staking replication of the glass patterns and narrow profiles of traditional single glazing, including elegant glazing bars, ovolo detailing, and curvaceous horns.

Our dedication to the conservation of London’s original aesthetics means that your replacement will be like-for-like, allowing you to enjoy the modern benefits of double-glazing, without compromising the appearance of your period property.
