If you are having issues caused by the wind, installing a Vacu-Stack will help with draft issues. Designed to create a vacuum and suck gases up and out of the chimney, the stronger the wind blows, the more powerful a vacuum it creates. 

Various names: Vacu-stack, wind cap, chimney wind cap, backdraft cap, wind beater caps.

Uses: Prevent wind-induced downdrafts, dynamic wind loading, wind blanketing, and other issues concerning fireplaces on a windy day.

Material used: Stainless steel.

Warranty: Lifetime.

Why purchase: If you notice that your chimney has drafting issues on windy days, this vacu-stack will likely solve the problem.

Here’s how it works: 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. This cap also functions as a conventional chimney cap by protecting the chimney from rain, snow, debris, and animals.
