Casement Windows

The simple design of casement windows means they can be installed in various types of property. In addition, casements can be made using a range of different configurations, ensuring they are an adaptable option for new-build applications as well as replacement windows.

French Windows

The Designer Door Company’s French Windows are stylish, safe and adaptable, adding a sense of elegance and class to any home. Our French Windows come with two outward openings, and the ability to open one or both sides simultaneously. This maximises ventilation potential and fire escape capabilities.

Tilt & Turn Windows

Tilt and turn windows are an ideal solution for a hard to reach area. This is because the window can be tilted into a room to allow for easy cleaning of the outside glass from the inside.

Shaped Windows

Our Shaped Windows can create an exclusive vibe for any newly built or period home. We use advanced moulding and forming window design technology, which allows us to create frames in virtually any shape.
