A casement window is a classic and versatile type of window, hinged at the side and designed to open outward like a door. Known for their elegance and functionality, casement windows have been a popular choice for homes and buildings for centuries. Their timeless appeal, combined with modern innovations, makes them an excellent option for both traditional and contemporary properties.
Throughout London, the team at Tusk Joinery & Restoration are well known for providing high-quality sash windows – both timber and uPVC – but did you know we also specialise in casement windows too? Our team has put together this helpful article to tell you everything you need to know about casement windows – or you can contact us now to find out more.

The History of Casement Windows
Casement windows trace their origins back to the medieval period, making them one of the earliest window styles in history. In their earliest form, these windows were crafted with wooden frames and featured leaded glass panes. Hinged along the side, they were often small and practical, allowing for ventilation and natural light in castles and cottages alike.
During the 17th and 18th centuries, casement windows evolved in design, becoming larger and incorporating finer materials. As glass manufacturing advanced, the panes grew clearer and more robust. Today, casement windows remain a symbol of heritage architecture while adapting to meet modern standards of performance and energy efficiency.
How Do Casement Windows Operate?
Casement windows operate using a simple yet effective mechanism. They are hinged on the side and typically open outward, similar to a door. This design allows for maximum ventilation, as the entire sash can swing open to let fresh air into the home. Casement windows are often operated with a crank handle, which makes them easy to open and close, even in hard-to-reach places.
Modern casement windows may also include friction stays or other innovative hardware that ensures smooth operation and keeps the sash secure when open. Thanks to their tight seals when closed, casement windows are highly effective at keeping out draughts and maintaining indoor temperatures, making them a practical choice for energy-conscious homeowners.

Types of Casement Windows
Casement windows come in a variety of designs, each tailored to suit different architectural styles and functional needs:
Side-Hung Casement Windows: Hinged on the side and opening outward, these are the most common type of casement windows.
Top-Hung (Awning) Windows: Hinged at the top, these windows open outward from the bottom, offering ventilation while keeping out rain.
Fixed Casement Windows: These do not open but serve as decorative or functional features to bring in light and provide an unobstructed view.
French Casement Windows: Featuring two sashes that open outward without a central mullion, these windows provide a wide, clear opening.
Each type of casement window offers unique benefits, making it easy to find a style that complements your home and meets your practical needs. From classic designs to modern innovations, there is a casement window for every preference.
