What Are Wind-Directional Chimney Caps?
Wind-directional chimney caps (sometimes referred to as draft-increasing chimney caps) are designed to withstand high wind conditions, prevent the wind from going down your flue and causing cold downdrafts, and utilize the wind to create stronger updrafts. These chimney caps help your fireplace vent properly by forcing smoke upward and out of your chimney.
These benefits are possible because of the special design of the wind-directional chimney cap, which forces wind around the top of the chimney cap and does not let it enter the flue. The air velocity created by the wind reduces the static pressure above the chimney, creating a partial vacuum and forcing the smoke inside the flue upward. You can expect a better updraft the harder the wind blows.
Is a Wind-Directional Chimney Cap Right for Me?
Wind-directional chimney caps are an excellent option if you have issues with wind-induced downdrafts or have a draft-heavy fireplace. Wind-directional chimney caps are also a common choice for factory-built metal chimneys. We carry wind-directional chimney caps that are ideal for all conditions and different types of chimneys.
Additional Considerations
Wind-directional chimney caps may require regular cleaning to remove the deposits and smoke that accumulate in the spinning turbines.
Keep in mind that wind-directional chimney caps will only reduce drafts that are related to wind — not drafts related to chimney top pressurization (caused when tall objects surround your chimney) or air inversion.
