What are casement and flush casement windows?

Casement Windows

‘Casement’ refers to the part of a window that opens. Casement windows hang on hinges attached to their frame, allowing them to open sideways or from the top. They are one of the most popular types of windows in the UK and boast design variety, ease of use and energy efficiency.

Flush Casement Windows

Unlike casement windows which have the openable parts protruding from the frame, flush casement windows are designed to lay flat against the wall. This creates a smooth, flat surface on the building exterior without any overlap.

What’s the difference between casement and flush casement windows?

Your Choice of Casement Window Finishes

Our casement windows are available in uPVC or aluminium with a variety of colour choices and have the option of double or triple glazing. We fabricate our windows using premium quality materials sourced from the leading suppliers in the industry. These hard-wearing materials mean our casement windows are highly insulating, extremely durable, and virtually maintenance-free. Once they arrive at your home, our window installers will verify the fit. All windows come with toughened safety glass where required, trickle vents and window restrictors which add value to your new windows.

What are the benefits of casement windows?


When casement windows are closed, they form a tight seal. This helps to keep your home insulated and draught-free – therefore saving you money on your energy bills!

Bespoke Design

Replacing old or aged windows with new, made-to-measure ones gives you the chance to put your stamp on your house. Our bespoke casement window design lets you do just that!

Enhanced Security

Our casement windows include toughened safety glass if required and multi-locking points so you can enjoy enhanced home security

Maximum Ventilation

Casement windows offer a lot of ventilation as they can be fully opened. This makes them ideal for rooms that get stuffy, such as kitchens and bathrooms.


Our casement windows are water-resistant and don’t absorb water in the ways that wooden windows do. This means they’ll maintain their functionality for years.


Our casement uPVC or aluminium windows can last for over 30 years if they’re maintained properly. This means that they are a fantastic investment!

Low Maintenance

As casement windows open outward, you’re able to easily clean them from the inside as there are no ledges in the way.

Simple Installation

With our experience and skill, we can quickly and easily install your new windows for a completely hassle-free experience.
