What Are the Parts of a Chimney?

Chimneys have been an important feature of homes for centuries, creating a cozy and inviting atmosphere for families. While many homeowners enjoy the warmth of their chimneys, they do not know the parts of a chimney. It is important to know the parts of a chimney because it can help homeowners understand how their chimney works and identify any potential problems or maintenance issues. A chimney is a complex system that consists of several components. At Town and Country Chimney, we have been providing homeowners with chimney services for years. We wanted to talk today about the different parts of a chimney.

Chimney Cap

The chimney cap covers the opening of the chimney, and it helps to prevent debris, rainwater, and animals from entering the chimney. Foreign materials entering a chimney increase the risk of a chimney fire. Chimney caps are typically made of metal, such as steel or copper. They come in various shapes and sizes to fit different types of chimneys and match the exterior of any home. 

Chimney Crown

The crown is a concrete or mortar cap that sits on top of the chimney and helps to protect the chimney from water damage. The chimney crown is constructed with a slope that allows water to run off and away from the chimney. It also extends past the edge of the chimney, providing extra protection against rain and snow.

Chimney Flue

A chimney flue is a passageway inside a chimney that allows smoke and gases to escape from a fireplace or stove. The flue is typically constructed of clay tiles, stainless steel, or other heat-resistant materials. It extends from the top of the chimney down to the fireplace.

Chimney Liner

A chimney liner is a protective barrier inside the chimney that helps contain the heat and smoke within the chimney. It adds an additional layer of defense and lines the interior of the chimney from the flue collar to the top of the chimney. A chimney liner can improve the efficiency of a chimney by helping to maintain a consistent draft and reducing the amount of heat lost to the chimney walls. 

Smoke Shelf

The smoke shelf is a horizontal ledge located just above the damper that helps to collect any debris that may fall from the flue liner. It also helps stop downdrafts in the chimney from making it out of the fireplace and into the home. 


A chimney damper is a metal or ceramic plate that is installed inside the chimney flue, usually just above the firebox. The damper can be opened or closed to control the flow of air and smoke in and out of the chimney. When a fire isn’t being run, the damper seals the chimney so cold air stays out and the home stays warm.
