What are Andersen Big Doors?
Big Doors are Andersen's large-scale door systems designed to open up an entire wall. They include folding (bi-fold) glass walls, multi-glide sliding doors, and oversized pivot doors.
What is the difference between folding and multi-glide doors?
Folding (bi-fold) doors are hinged panels that fold and stack to one side, fully opening the span. Multi-glide doors slide along tracks and can stack or pocket into the wall. Both create a wide, seamless opening to the outdoors.
Are big glass walls energy efficient?
Yes. Andersen Big Doors use insulated glass and weather-tight seals engineered for large openings, so you get the dramatic indoor-outdoor connection without sacrificing comfort.
How wide can Andersen Big Doors span?
These systems are built for large openings far beyond a standard patio door. Exact spans depend on the system and configuration — we'll help you design an opening that fits your space and structure.
Does Emerald City Energy install Big Doors and moving glass walls?
Yes. We design and install Andersen Big Doors and other moving glass wall systems throughout Seattle, Tacoma, Bellevue, and the Puget Sound. See also our moving glass wall systems page.
