Box Sash Window v Sliding Sash Window

What is a box sash window and what’s the difference between box sash windows and sliding sash windows ?

Sash Windows

A sash window has an elegant design and has been very popular since the 17th century with its sliding “sashes” that move up and down to open and close the window as required. They have a distinctive, characterful style being  highly sought after (and often required by local conservation areas) and best suited to period properties.

Box Sash Window or Sliding Sash Window ?

Box sash windows are very traditional but are often bulky and over time sash cords can become worn and need to be replaced when they become stuck or difficult to open.

The traditional weights and pulleys systems used in the past are often replaced with a more modern method using spiral balances which includes the use of springs. Such advanced technology allows manufacturers, like us, to replace authentic box sash windows with the benefit of modern performance levels of sliding sash windows.
