The Stoll AirSeal option is available in Bifold style doors. These doors feature gasketing between the glass and the door frame, as well as between the door frame and the main frame. Bifold AirSeal doors must have a metal bar at each glass joint to seal properly. AirSeal door frames are 1-1/4" wide instead of the standard 1" width of our regular glass doors. Vertical bars at each glass joint are 1/2" wide.
