Distinctive Design and Impressive Craftsmanship

Introduced in the late 1600s, sash windows became a hallmark of Georgian, Victorian and Edwardian architecture. Numerous period properties have them, and they’re still widely used. What better way to frame glorious Devon scenery!

Sash windows’ distinctive design typically features two panels – the sashes – with either several small panes or large sheets of glass. One or both sashes can slide vertically within the frame. Thanks to our impressive craftsmanship, your timber sash windows will glide smoothly, enabling you to open and close them with ease. When closed, the sashes can be locked together for security.

The sashes’ movement is facilitated by spiral balances in our sash windows, while weights perform this role in our box sash windows. The most obvious difference between a sash window and box sash window is the latter requires a more imposing frame to conceal the weights.
