Different Types of Casement Windows

Casement windows are usually fitted in double or single panels, and there are plenty of options to suit different-sized apertures and design preferences across all types and ages of property.

Casement windows are one of the most popular window choices because they are hugely versatile in design and configuration plus, they are available in timber, aluminium or uPVC.

Different Types of Casement Windows

• Side hung – this is the most common type of casement window, hinged at the side with the panel swinging outwards when open
• Single casement – a simple window comprising one panel with side hinges
• Double frame or French casement – a pair of panel windows that are both side-hung. There’s a central mullion between the two panels with the window handles in the middle. Both windows open outwards to create a large aperture
• Top hung or awning window – this casement style is a window that opens from the bottom and is hinged at the top. The window swings outwards so it protects the interior from rain
• Bottom hung or Hopper window – the window opens at the top of the frame with a hinge at the bottom. This style of casement is ideal for apartments and rooms on upper floors and allows safe opening
• Flush casement – a flush casement has a sleek frame, and the window sits flush in the frame when it’s closed. This is a particularly popular style for contemporary properties and works well with aluminium frames that have a slim profile
• Fixed casement – this is usually one panel in a more extensive configuration and commonly the central panel which doesn’t open, with opening sections on either side

Casement windows don’t have to be square or rectangular; they work particularly well for arched or gothic windows.

The Difference between Flush and Lipped Casements

A flush casement window is where the panels are flush with the frame externally. Lipped or storm-proof casements have a different design where the sash overlaps the frame. Flush casement windows are generally considered less weather-resistant, so fitting good seals is essential to keep out draughts.

Do you always need a Stay on a Casement Window to Hold it open?

You can have a traditional stay, or some manufacturers use egress friction hinges where the friction of the hinge holds the window in place when open.

Safety and Security

Some casement window designs feature a secure night vent positioning so you can receive the benefits of fresh air ventilation without needing to worry. You can also fit casement windows with child safety restrictors. For optimal protection, choose high-security multipoint Espagnolette locking handles where the lock is contained within the handle hardware.

Versatility and Flexibility

Casement windows offer infinite possibilities when it comes to the choice of glazing and the dimensions and arrangement of the glazing bars. Homeowners can create contemporary or heritage designs to suit their property with a window style that is high-functioning and practical, as well as offering an excellent design aesthetic.

The Advantages of Casement Windows

Casement windows are one of the most popular and cost-effective window choices for your home. They offer ideal ventilation, and if you have a top-hung casement, then this allows a steady flow of air without draughts. Easy to use and secure, they offer excellent uninterrupted views when open, and if you limit the number of glazing bars, you can retain this when the casement is closed. Finally, casement windows have one of the best security profiles for home protection.
