This Vacu-Stack Air Cooled Chimney Cap features a unique design that actually increases 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.
