When it comes to the different parts of a chimney, it can be easy to get confused. Especially if you do not understand exactly what each part does. Also, it can be difficult when a part seems to do the same function as another part. Then you realize it ends up being called another name. Learning what each individual part actually does makes it much easier to see the importance of each part. You can also see the functions that make parts different from each other.

Chimney Cap Vs. Spark Arrestor

Many people tend to confuse chimney caps with spark arrestors. This is because they both sit on top of the chimney. However, not all chimney caps are equipped with the mesh metal siding that spark arrestors must have. American Chimney & Masonry sells both of these chimney components. So now we would like to explain the differences to you.

What Is A Chimney Spark Arrestor?What is a spark arrestor on a chimney?

Spark arrestors keep sparks and embers from landing on the roof or on combustible material on the ground to start a fire. Chimney spark arrestors generally consist of double layers of metal mesh. This mesh can catch embers, yet still allow gases and smoke to exit the chimney. As defined by Wikipedia, a spark arrestor is “any device which prevents the emission of flammable debris from combustion sources.” They go on to say that spark arrestors are fitted to a chimney to keep sparks and embers from jumping out of the chimney.

Do chimney spark arrestors have other functions?

The metal meshing on a chimney spark arrestor is great to prevent birds, squirrels, raccoons, and other wild animals from being able to get into the chimney to nest. Without this type of protection on your chimney, these critters can enter your flue to cause problems in your chimney and could even become trapped.
