The Difference Between Exterior and Interior Spark Arrestors

We often emphasize this fact with customers: “A fireplace in a home poses no more danger than any other natural gas heating system.” We then add this caveat: “…provided it receives maintenance and has the proper safety precautions installed.”

If you have a wood burning stove or fireplace, a key safety device is the spark arrestor, which helps prevent embers that can cause fires inside your home, or in combustible material (scrubs, brush) right outside your home. If your home’s fireplace lacks spark arrestors, you need to have them installed as soon as possible to keep your hearth and home safe. Call 2nd Generation Chimneys, Inc., where we offer full installation of a variety of fireplace spark arrestors in St. Paul, MN.

There are two types of spark arrestors, interior and exterior, and your home needs both.

Interior spark arrestor

These are often known as “hearth screens,” barriers that prevent embers from leaping from the fireplace and igniting flammable material. These screens can consists of sliding glass doors, metals screens and curtains. Arrestors can be designed to be part of the attractive décor of the fireplace, but they must also be carefully fit and installed for the type of wood that will be burnt in the fireplace, and to make sure the chimney receives proper ventilation. These arrestors are also important for the safety of children and pets in your home. Make sure that you receive professional installation for your interior spark arrestor so that it does the multiple jobs that it needs to do, while still adding to your home’s beauty.

Exterior spark arrestor

The big difference between the interior and the exterior spark arrestors is that the exterior arrestors serve no decorative purpose at all. For the most part, you will not actually see the exterior arrestor. These safety features are attached to the chimney cap or rain cover, and take on the combined tasks of preventing the escape of embers from the top of the chimney, stopping animals from entering the flue, and keeping out rain that will create moisture inside the mortar leading to cracking. If you already have a spark arrestor installed for the chimney, make sure that you schedule regular inspections to see that it is in good condition.

If you are unsure about your fireplace spark arrestors in St. Paul, MN (for example, you don’t know if you have an exterior spark arrestor or not), call 2nd Generation Chimneys, Inc. today. We can examine your fireplace and chimney to see if you need installation, replacements, or repairs.
