Automatic door bottoms are a more advanced option that offers a blend of aesthetics and functionality. They include a mechanism that raises the seal when the door is opened and lowers it when the door is closed. This flexibility means that the seal will not wear down from constant contact with the floor. Automatic door bottoms provide high energy efficiency and are ideal for spaces that require sound insulation, like offices or music rooms.
