What are wooden sash windows?

Wooden sash windows are fitted in both traditional, historic homes as well as more modern properties and are, essentially, wooden windows that feature at least two vertically sliding panels.

Wooden sash windows can be referred to as vertical sliding sash windows, hung sash windows or box sash windows.

Wooden sash windows can be:

-Single hung (one moving panel, usually the lower panel)

-Double hung (two panels, top and bottom)

On rare occasions, the windows can be triple or quadruple hung which can be made to order (3 or 4 moving panels).
