UPVC Casement & Sash Windows


A casement window (or casement) is a window that is attached to its frame by one or more hinges. Casement windows are usually hinged at the side however, class windows hinged at the Top using our Casement profile as Casement also instead of the historical and traditional term “awning window”. Our Casement windows are hinged internally so that the hinging mechanisms are not exposed to the elements and these hinge mechanisms are built to have an adjustable friction stay to allow for smooth and friction-less movement.

Historically in the United Kingdom, Casement windows have been the most common house window, this was before the introduction of the sash window in the 17th Century. However, through continual development the Casement has seen a resurgence in the 20th and 21st Century and has become again the most popular choice due to versatility and cost. Its constant development within JWS has seen improvements in the weather seals between glass and frame and frame and frame. We have also made significant improvements in the locking mechanisms and incorporated these locking features to improve the overall security and weather seals of the window.

Sash windows could have been invented as early as the 17th Century in England. Another school of thought suggests that sash windows originated in France and spread to England via Holland. The word “sash”, derived from the French “chassis”, means frame. A sash window or hung sash window is made of one or more movable panels or “sashes” that form a frame to hold panes of glass.

The heritage range uses PVCu over timber enabling us to use traditional vertical sash manufacturing methods combined with the maintenance free properties of PVCu.

Manufacturing this way ensures superior thermal retention properties, excellent weathering performance over time and very low maintenance for the customer, all without losing the traditional character of a sliding sash window.
