Double casement windows are a timeless, traditional type of window that have been used in properties for hundreds of years, proving popular across many different architectural eras.
In this article we explore the benefits of double casement windows, which include durability, energy efficiency, security and ventilation.
What is a double casement window?
Double casement windows are a type of traditional window that consists of two opening casements with single or double-glazed panels. These are inset on a pair of hinges that open and close like a pair of double doors from the side or from the top.

● With or without a central post (mullion)

Benefits of a double casement window
There are many benefits to installing quality double casement windows, including authenticity, durability, and high performance.
Authentic design
As double casement windows would have originally been made with timber in the Georgian, Victorian and Edwardian eras, timber is the authentic choice that is most faithful to the original architecture and will also add the most value to your property. Unlike other choices such as uPVC, timber casement windows can be made in slim, elegant sections to carefully match the original windows.
Durability
Our timber casement windows are durable because they are made from high performance, stable timbers such as Accoya and designed to last. Wooden-framed double-glazed casement windows can last up to 100 years if well-maintained.
Easy cleaning and maintenance
The outward-opening design ensures all parts are easily accessible for cleaning. Clean windows and frames make all the difference to the appearance of your casement double window. Keeping your glass and frames clean means, you can prevent deterioration before it happens. Wooden windows that are not regularly cleaned can encourage mossy growth, which can destroy the seals and allow in draughts.
Energy efficiency
All our casement windows are precision crafted with our commitment to quality. Our commitment to energy efficiency comes from bespoke designs, high-performance glazing options, and full perimeter draught-proofing. Our slim double glazing includes options for both superior sound and thermal insulation. The combination of insulating factors means you can reduce your energy bills as well as being more eco-friendly.
Enhanced ventilation
This is created by the fully opening design that promotes enhanced ventilation by allowing maximum airflow through your home, and concealed trickle vent options for when the windows are closed. Our thoughtful designs are made to be energy efficient with the ability to enjoy ventilation when needed as well as reduce unwanted draughts.
Improved view
For double-glazed casement windows without a central bar, known as a mullion, there is an unobscured view or panorama when the windows are open. The authentic heritage design of our casement windows includes slim sections and frames, to maximise the size of the glazed area and therefore the view and the amount of light in your home.
High security
We take security seriously with multi-point locking systems and high-quality ironmongery to promote stability and peace of mind. Our bespoke double window designs include reinforced frames and options for laminated security glazing with a commitment to robust, traditional joinery techniques and enhanced attention to detail to provide a robust barrier protecting your home.
