The vertical sash window is often found in Georgian and Victorian styled properties and is most commonly made up of two sashes that slide up and down.  The modern sash window retains traditional aesthetics but has improved functionality, performance and security.


Sliding sash windows are among the most coveted window styles, not only due to their aesthetics, but also due to their historical association with style and wealth. They are of course the default choice for heritage buildings, whereas casement windows are preferred for more contemporary homes.

Whilst casement windows do date back to before Victorian times, when the sash window grew massively in popularity, sash windows are a clearer choice for historic buildings as they have connotations with royalty and nobility. Sash windows are not just for heritage buildings however, they can also add a touch of class to any home.
