French Windows

This window design is also known as a Floating Mullion Casement Window as it allows both window sashes to open fully at 90 degrees with the centre bar ‘floating’ on the slave window, much like a pair of opening-out doors.

       

Special hinges allow the sashes to open at 90 degrees to give uninterrupted views through the window opening. When closed, the window looks like a standard casement window. Another benefit of this window design is it can be used to offer a fire escape when both sashes are open fully.
