Bi-Fold Door

Style: C 8000

Walls divide, but adding bi-fold doors from Portella seemingly eliminates them, connecting you in amazing ways to your surroundings. Mounted on a smooth track, our bi-fold doors effortlessly fold into each other to open up or close off any great room, living room or entertainment space while allowing full, unobstructed light—and your view—to shine through. We can design your doors to open from one side or in the middle, whatever you need to fit your space. Finish your doors with custom hardware to create a flush sill or step—both fold virtually out of sight.
