Designed on the fulcrum principle, balanced doors assist opening in specific site circumstances of wind tunnel or stack effect. The design uses the differential of interior and exterior air pressure to facilitate opening of the door. The design features a sliding pivot located at the third point in the door header. The imposed forces, whether wind or stack draft suction are balanced on each side of the pivot in a 'see-saw' fashion. The imposed load on one side tends to open the door, while the load on the facing side forces the door closed. Less force or strength is required to open the door and the movement is well controlled.
