This project is for a Georgian villa in the United States. Our main products include sliding doors, fixed windows, folding doors, and French doors.
That's an interesting observation! While Americans don't literally use "doors as windows," what you're likely noticing is the popularity of large glass doors (like sliding glass doors, French doors, or patio doors) that function similarly to very large windows. Here's why they're so common:
Blurring Indoor/Outdoor Living: Americans often value strong connections to their outdoor spaces (decks, patios, yards). These large glass doors provide expansive views and easy access, making the outdoors feel like an extension of the living area.
Abundance of Natural Light: They allow massive amounts of natural light to flood into interior rooms, making spaces feel brighter, larger, and more welcoming. This is highly desirable.
Focus on Backyards: Especially in suburban areas, the backyard is a major focus for relaxation, entertaining, gardening, and play. Large doors provide the perfect vantage point and access point to this private outdoor space.
Architectural Style: They fit well with popular American architectural styles like Ranch, Contemporary, and many modern designs that emphasize horizontal lines, openness, and integration with the landscape.
Functionality: Unlike a fixed window wall, these doors actually open. Sliding doors save space (no swing), while French doors offer a classic, elegant look. Both provide ventilation.
Climate: In many parts of the US (like California, the South, Southwest), the climate allows for these doors to be used frequently throughout much of the year without excessive heat loss or gain concerns (though energy efficiency is still a factor).
Perception of Space: They make interior rooms feel significantly larger and less boxed-in by visually expanding the space to the outdoors.
In essence, it's not that doors are replacing windows, but that large glass doors serve a dual purpose: providing significant window-like benefits (light, views) while also offering crucial door functionality (access, ventilation) to connect the home to its outdoor living areas. This combination is highly valued in American residential design.
