Cold Weather Package - Easy to Insulate
All of our automatic Bi-Fold Doors are easy to insulate with blanket, foil or hard board fitted between the door frame
members. The thicker the door frames, the more insulation you can apply. You can also place the insulation between
the door frame and the outside sheeting.
