The Vacu-Stack Air Cooled Chimney Cap is the best solution for wind induced downdrafts. It is designed to fit double or triple-wall, air-insulated, factory built chimneys to stop wind from blowing into the chimney regardless of the wind direction. By accelerating air flow around the Vacu-Stack, flue gasses are forced to flow up and out of the chimney.
This Vacu-Stack Air Cooled Chimney Cap features a unique design that actually increses the draft when the wind hits it as opposed to deflecting it down the chimney and overpowering the draft. A special large 16" bottom collar rests underneath the cap to keep rain from entering the air-insulated chimney and maintain the proper internal venting that is required.
