Side folding doors are stored (stacked) in a pocket or at the sides of the opening when in the full open position. Determining what layout to use depends on space limitations, type of closure and how you want the door to operate. When panels are stored they are referred to as a stack.

A variety of layouts are available for side-folding doors, including straight spans, stack arrangements, curves and special radius.

See "Layout" document for more information on layout options.
