uPVC French Window Designs to Suit any Hertfordshire Home

uPVC French Casement Windows take the best elements of the standard casement window and go one step further. The central mullion is removed from the equation with this design, enabling both side vents to open fully.

Our uPVC French casement windows operate in the same way as a French door. Incredible views come as standard with this style of double glazing, which opens fully to create clear views of the world outside your home.

Another advantage of the French casement window style is evidenced by its ability to function as a fire exit. This flexibility of design means it’s often installed in smaller openings – for example in bathrooms, where space is limited.
