French Windows

For projects that require a more traditional aesthetic, French windows offer a number of benefits including allowing lots of natural daylight into a property, providing increased ventilation, and can be designed to open inwards or outwards for extra flexibility. They also are used as a fire escape, satisfying fire safety and Part B regulations.

Available in a range of designs, sizes, styles and colours, our French windows are the ideal option, offering versatility, sustainability and energy-efficiency – all manufactured at our state-of-the-art fabrication facility.
