What Are Casement Windows?
Casement windows open on hinges placed at their sides and are designed for maximum ventilation, view, and weather tightness. Our uPVC casement windows offer longevity and efficiency, making them suitable for both modern and traditional houses.
Klassic Trade Frames offers casement windows in classical uPVC, timber, and aluminum, offering both traditional and modern looks. Any of our casement windows can be made with either double or triple glazing, offering great energy efficiency to your home or project.

When Should Casement Windows Be Used?
From traditional uPVC to contemporary aluminum casement windows, there is something for everyone, based on their preferences and requirements.

Living Rooms & Lounges
The uPVC casement windows are the perfect choice for letting more light into your rooms, creating large, precise window openings that connect the indoors with nature.

Kitchens
Great for installing above counters or sinks, the windows open easily to provide excellent ventilation. They will help you keep your kitchen clean and airy.

Bedrooms
Ideal for installing above counters or sinks, the windows can be easily opened to ensure adequate ventilation, keeping your kitchen clean and free of steam or other unpleasant smells.

Bathrooms
Casement windows with obscure or decorative glass will suit your bathroom well, as they allow both proper ventilation and privacy.

Stairwells & Hard-to-Reach Areas
Casement windows are great for hard-to-reach places because they require only one handle to operate.
