What is a uPVC Casement Window?

A uPVC casement window is the UK's most popular window style. Hinged at the side or top and opening outward, casement windows offer excellent ventilation, a tight weatherproof seal, and the versatility to suit almost any property type.

What sets uPVC casement windows apart from older timber or aluminium alternatives is the combination of a virtually maintenance-free frame with modern double or triple glazing technology, delivering warmth, security, and style in a single, elegant package.

Types of Casement Windows

Side-Hung Casement Windows

The classic configuration. Hinged on one side and opening outward, side-hung casements are the go-to choice for bedrooms, bathrooms, living rooms, and kitchens. Versatile and timeless, they work equally well in traditional and contemporary settings.

Top-Hung Casement Windows

Ideal for smaller openings or high-level windows, top-hung casements open outward from the bottom. The naturally limited opening angle provides an added layer of safety, making them a popular choice for children's bedrooms and above worktops.

French Casement Windows

Two side-hung vents with no central mullion. Both vents open fully outward, creating a wide, unobstructed aperture that floods the room with natural light and fresh air. A beautiful choice for garden-facing rooms, kitchen extensions, and period properties where character and ventilation matter most.

Flush Casement Windows

The sash sits flush with the outer face of the frame, closely mimicking the look of traditional timber windows. Ideal for period properties, heritage buildings, and conservation areas where appearance is as important as performance.

French Casement Windows: Beauty Without Compromise

Of all the styles in our casement range, French casement windows are among the most admired. With no fixed central bar dividing the frame, both vents open independently to create a full, unobstructed opening that maximises light, ventilation, and views.

Available in bevelled and sculptured profiles, A-rated as standard, and fitted with high-security multi-point locks, they're particularly well suited to country cottages, Victorian terraces, and any home where the windows are a defining feature of the building's character. They also make an excellent fire escape solution, meeting current building regulation requirements with ease.
