What Is a French Door?
A French door is a door style that features glass panes extending for most of its length, typically in a pair of doors that open from the center. Often used to connect indoor and outdoor spaces, French doors are celebrated for their ability to bring in natural light and enhance the aesthetic appeal of a home.
Unlike traditional solid doors, French doors add openness and elegance. When you choose Thermo-Seal, you get the added benefit of industry-leading thermal performance and advanced sealing that helps insulate your home year-round.
What Is the Difference Between a French Door and a Double Door?
While the terms “French doors” and “double doors” are sometimes used interchangeably, there are key differences:
- French doors are always glass-panel doors, designed to allow in light and typically used in both interior and exterior applications. They’re often associated with style and elegance.
- Double doors refer to any two adjacent doors that open from the center—this can include solid doors, paneled wood doors, or French-style doors.
French doors are a specific type of double door—but not all double doors are French doors. If you're looking for enhanced views, brightness, and an upscale appearance, French doors are the ideal choice.

CLIENT REVIEWS
What Our Clients Are Saying About Us
Thermo-seal Windows provides exceptional customer service alongside high-quality products. Recently, I had the majority of my home's windows replaced by Aaron's team, and their performance was nothing short of impressive. They arrived on time, maintained a tidy work area, and dedicated themselves to ensuring a perfect installation of the windows.
Aaron and his team were amazing, from start to finish! They worked with us every step of the way and Aaron was always just a call or text away to answer any questions we had. The windows are perfect and we love them. We highly recommend working with Aaron and his team. They are professional, courteous and their work is top notch!
