A casement window has one or more hinged sashes that swing open like a door, rather than sliding vertically like a sash window. The window sections are formed from solid timber and mortice and tenon jointed. Casement windows became more popular than traditional sliding sash windows as they were cheaper to manufacture, needed less maintenance and gave properties a more modern look, and they remain the most common window style built today.
Frame: the outer, fixed timber structure built into the wall opening.
Sash: the opening or fixed panel that holds the glass, hung within the frame.
Hinges: traditionally butt hinges fitted to the side or top of the sash, allowing it to swing open.
Casement stay: the arm that holds the open sash in position at a chosen angle.
Casement fastener: the handle that draws the sash shut against the frame and locks it.
Glazing bars: the narrow timber bars dividing the glass into individual panes.
Cill: the horizontal timber at the base of the frame that sheds water away from the window.
Casement windows suit both period and contemporary properties, and can be configured as a single sash, paired sashes, or combined with fixed lights and top hung vents above. Because the sash swings fully open, it gives an unobstructed opening for ventilation, and there is a wide choice of ironmongery available in different finishes to match the style of a property.
Casement windows are one of the areas we’re most competitive on, whether that’s a straightforward standard size for a new build or replacement job, or a design matched to what’s already on a period property. Every window is made at our factory in Chester, and pricing standard specifications sensibly is just as much a part of what we do as bespoke, one off work. You deal directly with the people building your windows from enquiry through to fitting.
