French windows, also known as fly mullion windows, feature two opening sashes with no fixed central post.
When opened, the entire aperture is clear, creating a wide, unobstructed opening that connects indoor and outdoor spaces seamlessly.
French windows provide maximum opening width, excellent ventilation, and an open, airy feel.
They are ideal for creating easy access to gardens, balconies, or terraces, while modern locking systems maintain high security when closed.
With strong thermal performance and elegant design, they offer both practicality and visual appeal.
