Aluminium sash windows are a popular architectural feature in the UK and other parts of the world. Sash windows are a type of window design that involves one or more movable panels, or “sashes”, that slide vertically or horizontally to open or close the window. These windows are known for their elegant and traditional appearance, and they have been used in British architecture for centuries. The addition of aluminium as a material for constructing sash windows brings modern benefits to this classic design.
