Some people know what a spark arrestor is. However, since today’s spark arrestors are normally combined with a chimney cap that also has a screen to keep critters and debris out of the flue, the term seems to get lost in translation. That’s too bad because a spark arrestor can potentially save your house from a fire and you should know exactly what it does.
What do Spark Arrestors do?
Spark arrestors play a critical role in the prevention of wildland fire and ignition of explosive atmospheres. As such, their use is required by law in many jurisdictions worldwide. Wikipedia says “A spark arrestor is any device which prevents the emission of flammable debris from combustion sources, such as internal combustion engines, fireplaces, and wood burning stoves.”
Specifically for buildings, Wikipedia says this: “Spark arrestors are also fitted to the top of a flue (or a chimney pot) to prevent floating embers from a fire (particularly one burning wood) setting light to a flammable roofing surface (shingle, thatch, or bitumen-felt) or falling onto combustible material on the ground. Such a spark arrestor typically consists of a double layer of metal mesh, which catches the ember and allows the flue gas to escape.”
Do I need a Spark Arrestor on My Chimney?
Making sure that your chimney system is equipped with a spark arrestor is essential in the protection of your home. That is why you need to make sure when you speak to your local chimney professional that they understand you want a chimney cap that is also rated as a spark arrestor. This chimney cap will include a mesh screen that will keep flying sparks from getting out of the chimney and landing on the roof. The great thing about these types of chimney caps is they will keep debris and also keep unwanted animals out of the flue, along with protecting the system from rain entering. Making sure you understand why chimney caps and spark arrestors are a necessity and not just add on features is very important to the overall safety of your family. Also it’s worth understanding about fireplace dampers – Top Mount Vs Throat Dampers.
