How do sash windows work?

A sash window comprises two panes, or sashes, that are manufactured in a way to slide open and closed. They are a traditional window design you are likely to see on homes in conservation areas. The window units sit in frames that allow them to slide effortlessly up and down; this movement is achieved through counterbalances used in their manufacturing.

How much do sash windows cost?

The price for your windows will vary depending on design, material, measurement and quantity. Because each project’s requirements differing, it’s difficult to give a straight figure. If you’re interested in receiving an estimated quote for your sash windows, please contact us.

Can sash windows be double glazed?

Yes. All of our sash windows come double glazed as standard, and some frames can even be triple glazed in addition. Talk to a member of our team to find out more.
