French Windows

World Group French windows - also known as 'flying mullion' windows - function in the same way as French doors. Each unit comprises a pair of PVC-U French windows that open outwards, offering an unspoilt view that's not broken by a central vertical frame member - or otherwise known as a mullion.

The result is a large opening space that offers uninterrupted vistas and improved air flow - ideal for the summer months when you want to bring the great outdoors into your home. Beautifully crafted, World Group French windows also have a symmetrical aesthetic appeal. An additional safety feature is that they can provide an alternative escape route from inside to outside - some people improvise and use it as a handy furniture entrance!

French windows are perfect for householders who want to fill a room with light and warmth in the summer months without losing any of the windows, energy efficiency in terms of thermal performance.
