Architect’s Corner
Bi-fold doors, also referred to as four-fold doors are an ideal choice when side space is available and there is a need for long lasting, low maintenance doors. With no springs to break and jamb the door, the bi-fold’s design is ideal for high cycle environments such as fire stations, parking garages, and auto dealerships.

SPEED

Bi-fold doors often open faster than a conventional overhead door.  Bi-folds operate at typical speeds of 24 inches per second compared to operation speeds of 8 to 12 inches per second for other door styles. A 14’ x 14’ bi-fold takes less than 7 seconds to open!

Faster operation has several key benefits including:

  • More throughput
  • Less energy loss
  • Greater security

For larger door openings and vehicles, the faster speed allows more vehicles to move through the opening. Because the door closes quicker, there is less opportunity for intrusion and less air loss; an important consideration for our harsh Minnesota winters.

HORIZONTAL MOVEMENT

The bi-fold door moves horizontally rather than vertically, making the door visible throughout the opening motion, and giving the diver a better view of the door clearance. With overhead doors drivers can misjudge the clearance available and drive into the bottom of the door as it is opening. In addition, bi-fold doors are more tolerant of dents and dings from impact in that the door will still continue to operate.
