Post by : dminCMC

Chimneys and fireplaces can be intimidating for homeowners, new and old. However, with chimneys being so critical to the internal structure and foundation of a home, it’s important to understand how they function.

Fortunately for you, we’ve combined a list of the most basic chimney and fireplace terms that you need to know as a homeowner!

Chimney Cap

A chimney cap is basically the roof of the chimney, and the opening is protected by the cap. Made of metal, chimney caps prevent the entry of unwanted debris, dirt, animals, rain, and snow into the house.

Chimney Crown

A chimney crown covers the entire top of a chimney and prevents water from entering. It typically has a chimney flue pipe in the middle.

Chimney Flashing

The flashing is a strip of sheet metal that covers the seam between the chimney and the roof. It can be made of aluminum, copper, steel, and is used to protect the chimney and roof from moisture and leakages.

Flue Pipe

A Flue is an opening duct or pipe that releases the smoke and toxic gases out of the chimney. This shaft allows for the ventilation of creosote and is located on the inside of the masonry chimney structure.

Chimney Liner

Chimney liners, often made out of long-lasting clay tiles, limit the fire to a chimney. Long-lasting and unique to each fireplace, chimney liners ensure proper ventilation in a home, and need to be in excellent condition to perform efficiently. They’re fire-resistance and cover the flue, while preventing the heat from the fireplace from damaging masonry walls and limits heat transfer to combustible materials.


The firebox or fireplace is where the fire burns and is made of firebricks and refractory mortar. These prevent heat transfer to the house and are an integral part of the whole chimney. It needs to be cleaned and inspected regularly to ensure proper functioning, and prevent the buildup of toxic gases in the home.

If you have a fireplace in your home that hasn’t been cleaned for a while, it’s critical that you have it cleaned ASAP to prevent damage to your home.
