Bi-fold doors consist of multiple hinged panels that fold against one another when opened, stacking compactly at one or both sides of the opening. When fully open, the door effectively disappears, making them a popular choice for entertainment-focused homes and projects where indoor-outdoor flow is a design priority. Available in wood, aluminum, and aluminum-clad configurations through Marvin Ultimate and NanaWall, with thermally broken frames suited to Canadian climates. Panel counts and total opening widths are highly configurable.
