Are Casement Windows Secure?

Casement windows rank among the most favored window types for residential settings, primarily for their security attributes. Equipped with multi-point locking mechanisms, they engage with numerous points around the window frame, significantly impeding any attempts by intruders to force them open. Moreover, many casement windows feature reinforcement with steel or aluminum, further enhancing their robustness and longevity. It's crucial to prioritize selecting a seasoned window installation company that adheres to all pertinent safety and security protocols when making your decision.

How long do Casement Windows last?

With proper care and maintenance, a well-made casement window made from materials such as uPVC or aluminium can last up to 20 years or more. uPVC casement windows hold the BBA accreditation, which means they can last more than 35 years with regular care.

How do you open them?

Casement windows operate by swinging outward on hinges positioned at the top or sides, which are manipulated using a handle. This design facilitates effective ventilation when the windows are opened and permits convenient cleaning of the exterior glass from inside the house. Should you encounter difficulties in opening your windows, we are available to assist you in identifying the problem and determining whether replacement is necessary.

How much do Casement Windows Cost?

The price of casement windows varies depending on the chosen material, whether it's uPVC, wood, or aluminium. Generally, white uPVC windows tend to have the most favorable pricing, followed by aluminium and then wood. Switching from pre-2002 double-glazed uPVC windows to A-rated double-glazed casement windows could potentially save you up to £184.25 annually*.

*This estimate is based on GGF data for a standard detached house with gas central heating, transitioning from double-glazed uPVC windows with a 12-14mm spacer bar to A-rated double-glazed uPVC casement windows.

What's the difference between Casement Windows and Sash Windows?

The primary distinction between casement and sash windows lies in their opening mechanism. While casement windows swing outward on a vertical hinge, sash windows move up and down on tracks within the frame. This feature can render sash windows more suitable for rooms where outward-opening windows are not feasible, such as spaces with restricted room or where the window might intrude upon a pathway or outdoor area.
