Sliding sash windows have been a significant feature of buildings in the UK since the 17th century. There are many variations of design details, such as the proportion of the panes within each sash, the width of the rails and glazing beads and the profile of the mouldings. Most sliding sash windows are now double-glazed.

In the past it was not possible to achieve good energy-efficiency without having over-thick glazing bars. Today’s double-glazed sliding sashes use one glazing unit for each sash. Within the glass sandwich of the glazing unit there is a grid of spacer bars that exactly matches the glazing bars applied to the surface. The effect is indistinguishable from individually-glazed panes and allows us to make sliding sash windows with authentic slim, period profiles, yet with A energy ratings or U-values as low as 1.2W/m2K.

Box sashes, using weights and pulleys are the traditional choice, but where space is limited, a modern spiral balance version is available.
Hardware can be traditional or modern. Windows can be supplied with locks, opening restrictors and enhanced security to meet Secured by Design standards.
