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. 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.

This is too keep them from landing on the roof or combustible material on the ground to start a fire. 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.
