Introduction to Casement Windows
Casement windows are one of the most popular window styles in the UK. Known for their practicality, clean lines and excellent ventilation, they suit both modern and traditional homes. Whether installed in a contemporary extension or a period property, casement windows offer a balance of performance and style.
The key appeal of casement windows lies in their ability to provide wide, unobstructed views and strong energy performance. Because the sash presses firmly against the frame when closed, it creates a tight seal that reduces draughts and improves thermal insulation. This helps maintain a comfortable indoor temperature throughout the year.
At Stroud Green Windows, we manufacture bespoke casement windows designed to enhance both appearance and efficiency. With high quality glazing, durable materials and secure locking systems, our casement windows are built to last.
What Are Casement Windows
Casement windows are hinged windows fitted with a sash that opens outward or inward from the side. The hinges are typically positioned vertically along one side of the frame, allowing the window to swing open like a door.
When closed, the sash locks tightly against the frame, forming an airtight seal. This design improves insulation and reduces heat loss compared to some other window styles. Casement windows are easy to operate, usually with a handle mechanism that allows smooth opening and secure locking.
Across the UK, casement windows are commonly installed in kitchens, bedrooms and living areas. They are particularly useful in areas where ventilation is important, such as above sinks or worktops. Their versatility means they can be adapted to a wide range of property styles.
Why Casement Windows Are Popular
Casement windows remain a favourite choice among homeowners for several reasons.
Style appeal
Casement windows offer a timeless look. With slim frames and clean profiles, they complement both period and contemporary architecture. Their simple design allows for larger panes of glass, maximising natural light and improving visibility.
Versatility in architectural design
Whether your home is a Victorian terrace, a modern townhouse or a suburban semi detached property, casement windows can be tailored to suit. They can be manufactured in various sizes and configurations, including single pane, multi pane or decorative glazing bar designs.
Availability in different frame materials
Casement windows are available in timber, aluminium and uPVC. Each material offers unique benefits in terms of durability, maintenance and performance. This flexibility makes casement windows suitable for a broad range of budgets and design preferences.
The 3 Must Have Types of Casement Windows
Single Frame Casement Windows
Single frame casement windows are the most traditional form of casement window. They consist of one main frame with one or more glass panels known as lights.
These windows open either inward or outward depending on the design. They provide excellent ventilation because the sash can open fully, allowing fresh air to circulate.
Key benefits include strong durability due to the hinged design, reliable weatherproofing and affordability compared to more complex window systems. Single frame casement windows are ideal for homeowners seeking a practical and cost effective solution.
French Casement Windows
French casement windows feature two sashes hinged on opposite sides of the frame. When opened, both sashes swing outward, meeting in the centre when closed.
This design creates a wide opening without a central mullion, offering an uninterrupted view and increased ventilation. French casement windows are particularly popular for properties where symmetry and visual balance are important.
Key benefits include large openings that allow maximum airflow, enhanced aesthetic appeal and improved natural light. They are also easy to clean and provide a stylish alternative to traditional single casement designs.
Push Out Casement Windows
Push out casement windows combine classic design with modern functionality. Instead of using a crank mechanism, these windows open using a handle that moves between turn, tilt and lock positions.
This style allows the window to tilt slightly for controlled ventilation or open fully for greater airflow. Many push out casement windows include multi point locking systems for enhanced security.
Key benefits include smooth operation, improved security features and an uncluttered design with minimal hardware. Their clean lines make them suitable for both contemporary and heritage properties.
Choosing the Right Casement Window for Your Home
Selecting the right casement window depends on several factors.
Style is a major consideration. A period property may benefit from timber casement windows with traditional detailing, while a modern extension may suit aluminium frames with slim sightlines.
Budget also plays a role. uPVC casement windows are often more affordable, while timber and aluminium offer premium finishes and extended durability.
Climate and exposure are important. In areas exposed to strong winds or heavy rainfall, high performance glazing and robust frames are essential.
House design influences choice as well. Larger openings may benefit from French casement windows, while smaller spaces may suit single frame designs.
