What are sash windows?
Sash windows are a traditional window system that slides vertically or horizontally within a frame for adjustable ventilation and closure. They are found in both residential and commercial buildings. Sash windows are particularly popular in period properties, where they match the traditional style and offer practical benefits.

Materials used to manufacture sash windows
Sash windows are made from several materials, with timber, aluminium, and uPVC being the most popular.
Timber sash windows
Original sash windows in Victorian and Georgian times would have been made from timber, making them the ideal choice for period and traditional homes. They provide an authentic aesthetic appeal as well as adding the most value to a property. With long lasting, durable timbers such as Accoya, and energy efficient slim double glazing, timber sash windows offer high performance and insulation as well as authentic design.
Historical usage
The exact origins of sash windows remain uncertain, with some attributing their invention to the Dutch and others to the French. The term “sash” is believed to derive from the French word chassis, meaning “frame.” Robert Hooke, a renowned architect, is sometimes credited with their development.
First appearing in the 17th century, sash windows spread from mainland Europe to the UK, where they became a preferred choice among the wealthy during the Georgian and Victorian eras. Still popular today, sash windows can be found in both traditional and modern properties, with historic examples preserved at Ham House (Richmond, London) and Palace House (Newmarket, Suffolk).
