Your Questions Answered by us
Casement windows are one of the most popular types of windows for residential properties due to their security features. They are fitted with multi-point locking systems that engage with several points around the window frame, making it difficult for an intruder to force the window open. Many casement windows are reinforced with steel or aluminium for added strength and durability. Choosing an experienced window installation company that meets all relevant safety and security standards should be an important part of your decision-making process.
Casement windows open outwards on hinges that open from the top or sides and are operated with a handle. When opened, casement windows can provide good ventilation and allow for easy cleaning of the exterior of the window from inside the home. If you’re having trouble opening your windows, we can help you diagnose the issue and whether you might need to replace them.
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. Anglian White Knight uPVC casement windows hold the BBA accreditation, which means they can last more than 35 years with regular care.
The cost of casement windows varies depending on whether you choose uPVC, wood or aluminium. White uPVC usually has the best price, followed by aluminium and then wood. Replacing your windows with Anglian A-rated double-glazed casement windows could save you up to £184.25 a year* when you upgrade from pre-2002 double-glazed uPVC windows.*Based on GGF data for a typical detached house with gas central heating upgrading from double-glazed uPVC windows with a 12-14mm spacer bar, to Anglian A-rated double-glazed uPVC casement windows.
The key difference between casement and sash windows is the way they open. While casement windows open outward on a vertical hinge, sash windows slide on tracks within the frame. This can make them a better choice in rooms where outward-opening windows are not practical, such as in rooms with limited space or where the window would encroach on a walkway or outdoor space.
