Sash Windows

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, including the narrow profiles of their single glazed counterparts: 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.
