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.


Emergency egress

Full-size door opens fully in direction of egress. Depending on locality, hardware and door should comply with ICBO and ADA egress requirements. Emergency Egress will add 8 to 10 inches of additional stack.

Special layout options

Side Folding Doors can fill irregular openings to maintain architectural integrity of a space including multi-level counter, sloping floor and more. Contact factory for special layout options.
