What Are Round High-Wind Air-Cooled Chimney Caps?
Wind-resistant chimney caps (sometimes referred to as high-wind chimney caps) are designed for protection from high wind-induced downdrafts, keeping them to a minimum by eliminating any path for outside air to flow down the chimney.
Our round high-wind chimney caps are designed specifically for both double-wall and triple-wall air-insulated (or air-cooled) metal chimneys. This kind of chimney features either two or three metal walls with open space between each, a design that promotes the cooling of the flue using air.
Unlike chimney caps that bolt directly to the flue or chimney crown, these round high-wind chimney caps slip right inside the flue’s opening (the interior pipe). To ensure a proper fit, measure the inside diameter of both the center pipe and the outside pipe.
Is a Round High-Wind Air-Cooled Chimney Cap Right for Me?
A round high-wind chimney cap is right for your home if you live in an area that experiences severe winds and have a metal air-cooled chimney. To determine if you have an air-cooled chimney, remove your existing chimney cap (if you have one) and check the pipe. Air-cooled chimneys have either double-wall or triple-wall pipes, so you should see two or three layers of pipe.
Alternatively, you can check your pipe by tapping its outside wall with an object such as a screwdriver. The pipe layers in double-wall and triple-wall pipes will vibrate, so if you hear vibrations, you know you have an air-cooled chimney.
Additional Considerations
These round high-wind chimney caps can only be used for air-cooled metal chimneys.
