uPVC French Casement Windows

uPVC French casement windows are very similar to the classic casement windows, but function in a manner not dissimilar to French doors. The two sashes operate as a primary and secondary leaf, opening wide to a 90° angle. This creates a large open area and a great sense of space.

Completely uninterrupted views are achieved as uPVC French casement windows do not contain a central bar. The flying mullion divide is instead attached to the master sash, resulting in a superb unobstructed view when fully opened and with a minimal, slim sightline when closed.

French casement windows are commonly found in upper level windows and are an ideal solution for double glazed windows situated on roofs, such as dormer windows. Not only do they provide excellent ventilation control, they can also be used to create an emergency exit.

As with the classic casement windows, they are suitable for any type and style of property both traditional and contemporary. Available in a range of colours to suit your individual requirements, our uPVC French casement windows are a sleek, stylish additional to any home in Kent.

Stunning Views

When opened fully, uPVC French casement windows provide clear uninterrupted views. With both sashes being able to be opened wide to a 90* angle, you’ll benefit from a large open area that will provide you with a sense of spaciousness that will make even the smallest of rooms feel bigger.

Triple Glazing

To further improve the energy efficiency of your home, you have the option of choosing triple glazing. The benefits of this additional are threefold. Take advantage of a warmer living environment, reduce the cost of heating your home and strengthen the security of your property.


Our uPVC French casement windows provide excellent, controlled ventilation for your home. The master sash can be opened independently from the slave sash, providing you with variable ventilation control. You can benefit from secure ventilation and allow the circulation of fresh air around your home.

Emergency Exit

Our uPVC French casement windows open wide to 90° angle, allowing for easy access in case of an emergency. These windows are perfect for smaller, narrower openings as they can be used as fire escapes and are compliant with building regulations Part B. This allows them to be incredibly versatile.

Due to the mullion divide being attached to the master sash, there is no central bar causing an obstruction. This allows for the maximum amount of natural sunlight to filter into your property, further enhancing the feel of the room and creating a better living environment.
