Casement Windows
Casement windows are one of the oldest and most enduring window styles in Britain. Unlike sash windows, which slide vertically, casement windows are hinged at the side and open outwards, making them practical, versatile and well suited to traditional homes.
The design became widely used in Britain during the medieval and Tudor periods, when windows were commonly made from timber and filled with small panes of glass. As glass manufacturing improved, larger and more practical casement windows became possible.
During the 18th and 19th centuries, casement windows continued to evolve and were widely used in cottages, townhouses and country properties. Their simple design made them particularly popular outside the grander Georgian and Victorian buildings where sash windows were often preferred.
By the 20th century, casement windows had become one of the most common window styles in British homes. Advances in manufacturing introduced new materials, including steel, aluminium and uPVC, while retaining the basic hinged opening principle.
Today, traditional timber casement windows remain a popular feature of period properties. With appropriate repair, maintenance and draught-proofing, original casement windows can be preserved while improving their comfort, performance and longevity.
