What Are Round Chimney Caps?
Our round chimney caps are designed specifically for Class A chimney pipes along with both double-wall and triple-wall air-insulated (or air-cooled) metal chimneys. We classify the round caps into two different segments: non air-cooled and air-cooled.
Non air-cooled caps usually go on a wood stove pipe that sticks up above the roof. This type of pipe is referred to as a Class A chimney pipe. Air-cooled chimneys are usually part of a factory-built chimney or prefab chimney. 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 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 Chimney Cap Right for Me?
A round chimney cap is right for your home if you have a metal air-cooled or non 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 if your chimney is air-cooled 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.
A non air-cooled chimney pipe is just a solid pipe without multiple layers with air space in between them.
