What Is the Purpose of a Chimney Cowl?

A cowl is a conical cover or structure used to prevent wind or rain from entering a hole or building. They are commonly used on top of chimneys, but can also be used on any similar opening such as an unused flue or skylight.

The primary purpose of a chimney cowl is to keep the wind from blowing down the chimney. This is accomplished by the cowl's aerodynamic design, which forces the wind to swirl around the outside of the cowl instead of entering the chimney. The cowl also doubles as a spark arrester, keeping hot ashes and embers from blowing out of the chimney and onto the roof.

Some cowls also have rain shields that deflect water away from the chimney opening. This is important to keep water from entering the chimney and causing damage to the structure or promoting the growth of harmful mold and mildew.

Cowls come in a variety of shapes and sizes to fit different types of chimneys. The most common type of cowl is the basic cap cowl, which is a simple cone-shaped cover that sits on top of the chimney. More elaborate cowls may have multiple parts that fit together to create a more effective wind barrier or may have special features such as baffles to deflect rain or screens to keep birds and other animals out of the chimney.

regardless of their design, all cowls serve the same basic purpose: to keep the elements out of the chimney so that it can function properly.

Chimney cowls are usually placed on top of chimneys to keep birds and animals from nesting inside, and to keep rain and snow from entering the chimney. They come in many different sizes and shapes, but all work in basically the same way.

The most common type of chimney cowl is the rain cap. It has a metal screen or mesh that covers the opening of the chimney, and a hood that extends out over the top of the chimney. The hood is usually made of metal, plastic, or fiberglass, and has a series of ridges or fins that deflect rain and snow away from the chimney opening.

Another type of chimney cowl is the bird guard. It also has a metal screen or mesh that covers the chimney opening, but the hood is much larger and has a more solid structure. The sides of the hood are vertical, and the top is sloped, so that it forms a kind of cage over the top of the chimney. The bird guard prevents birds from getting into the chimney, but it also keeps rain and snow out.

Still another type of chimney cowl is the spark arrester. It has a metal screen or mesh that covers the chimney opening, and a hood that extends out over the top of the chimney. The inside of the hood is lined with a wire mesh or screen. The spark arrester prevents sparks from escaping from the chimney and igniting a fire.

Chimney cowls are usually made of metal, but they can also be made of plastic, fiberglass, or wood. They come in many different sizes and shapes to fit different types of chimneys. Chimney cowls can be bought at hardware stores, home improvement stores, or online.
