What is French Doors?

French doors are hinged, double doors featuring glass panes extending for most of their length.


French doors, an elegant architectural element, connect various spaces while allowing natural light to flow freely from room to room. These hinged, double doors feature multiple glass panes - known as lights or lites - that typically extend for most of their length, enhancing the visual connection between indoor and outdoor spaces or between separate indoor areas. Traditionally, they open outwards or inwards and are often framed in wood, aluminum, or PVC, which can be painted or stained to match the interior design.

The glass panes in French doors can range from clear to frosted or patterned, catering to different privacy levels and design aesthetics. They are a popular choice not only for their functional benefits, such as maximizing natural light and improving ventilation but also for their ability to add a touch of elegance and sophistication to any space.


French doors are commonly used as exterior doors that open onto gardens, patios, or balconies, as well as interior doors to divide spaces such as living rooms and dining rooms or bedrooms and home offices. They are particularly popular in design styles that prioritize natural light and open, airy layouts, such as contemporary, minimalist, and coastal designs.

    French doors can be energy efficient if they feature energy-saving glazing options like double or triple glazing and proper sealing around the frames. The materials and construction play a vital role in their overall energy efficiency.

When incorporating French doors into a design project, consider the directional orientation to maximize natural light and energy efficiency.
