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.
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. 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.
Do chimney spark arrestors have other functions?
The metal meshing 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, these critters can enter your flue to cause problems and could even become trapped.
What exactly is a chimney cap?
A chimney cap covers the top of the flue. This is to keep water from rain, ice, and snow out of your home. The Chimney Safety Institute of America recommends it as the most economical way of preventing chimney water leaks. A standard chimney cap typically does not have mesh metal sides. However, American Chimney & Masonry carries a wide variety of caps that do! They can also serve as spark arrestors as well. These caps will also keep out wild animals and birds. We can also show you chimney caps that are equipped with special vents that will direct the wind to improve your chimney draft.
