What is a Sash Window?

What are sash windows?

Sash windows are windows that open vertically and have one or more moveable parts.

Commonly associated with traditional architecture and design, they contain two frames – one in front of another. More specifically, this is known as a sliding sash. The window units are positioned in frames with vertical grooves, which allow them to move smoothly and freely without causing frictional wear.

Counterbalances aid the seesaw movement of the sash.

These counterbalances may be exposed inside the window or hidden within the frame. Although these windows do not open on a hinge and do not have outward swings, their ability to tilt aids in cleaning. read more
