Vacu-Stack Chimney Caps for Wind Problems

The Vacu-Stack chimney cap solves wind-driven downdrafts by using the wind itself to create a vacuum effect, pulling smoke and flue gases up and out of the chimney no matter which direction the wind is blowing. A dependable fix for homes plagued by smoke or odor blowing back into the room.
