Vacu-Stack Chimney Cap

SKU: Vacu-Stack Chimney Caps

The Vacu-Stack Chimney Cap is used to stop smoking and decrease downdrafts caused by wind. To install gently slide Vacu-Stack down the pipe. Vacu-Stack also serves as a cap, keeping out rain, snow and critters. When wind flows around the Vacu-Stack's unique design, wind speeds increase which creates a partial vacuum. This vacuum then pulls flue gases up and out of the chimney, thus preventing wind-induced downdraft and the resulting infiltration of smoke, odor, and flue gas into your home.
