Frequently Asked Questions

What is a sash on a casement window?

Sashes are the framework holding the window panes together within the frame of a casement window. A sash is the ‘glass’ part of a casement window, which can be opened and closed by a simple handle. They are called ‘sashes’ as they have been traditionally made from wooden frames and fitted with glass, which is also often referred to as a sash. In modern times sashes are typically made from acrylic (Perspex) or glass.Casement windows are the most common type of window in use today. As a result, they are among the most familiar to the general public. They open by rotating outwards from a vertical plane and have hinges on the outside wall of the frame that enables this movement. Casement window frames can be one piece or be divided into two separate movable portions that may overlap (co-action casements). One-piece casements, as well as co-action casement sashes, are characterised by the overlapping portion that forms an aesthetic treatment of the joint between the two sash members.
