NGP Door Shoes, Bottoms and Sweeps

The bottom of the door is where most energy loss, sound transmission, and weather infiltration happens, and it's the hardest gap to seal because the door moves across it every time it opens. National Guard's door shoes, automatic door bottoms, and sweep products are engineered specifically for that challenge. Automatic door bottoms retract when the door opens and drop to seal when it closes, giving a clean threshold contact without drag on the flooring. Door shoes wrap the bottom rail and provide a continuous seal against the threshold profile below. Surface-mounted sweeps offer a lower-cost solution for interior and lightly exposed openings. National Guard makes products for wood, steel, and aluminum doors across residential, commercial, and fire-rated applications. Doorware.com carries the full National Guard sweep and door bottom lineup with trade pricing for contractors and building envelope specialists.
