Do you realize that the inside of your chimney has a liner? If so, have you ever considered insulating it? It may seem like an unusual question, but it’s a pertinent one nonetheless. Insulating your chimney works on the same principle as insulating your house. If you’re asking, “Do I need to insulate my chimney liner?” and remain unconvinced, read on—there are several compelling reasons to insulate your chimney.
Insulating a Chimney LinerIf you weren’t aware that your chimney has a liner, the idea of insulating it might feel like trying to understand quantum theory. But once your chimney liner is insulated, it’s relatively simple (pardon the pun). Let’s not put the cart before the horse—first, let’s explore what a chimney liner is and what it does.
A chimney liner is a long, flexible tube that runs the entire length of your chimney’s flue. Chimney liners are, with few exceptions, made from stainless steel, though some older homes may have liners made of ceramic or concrete. Chimney liners prevent high heat or deadly fumes from infiltrating your home. Now that you understand the importance of a chimney liner, let’s explore how insulating it can benefit you.
Insulating a chimney liner isn’t complicated, but it’s highly effective. The insulation wraps around the entire length of the chimney liner. Some liner insulation contains stainless steel fillers or ceramic fibers. A popular type of insulation is an insulation blanket, a thick fabric made from alkaline earth silicate.
There are several compelling reasons to insulate your chimney’s liner:
Studies show that insulating your chimney liner significantly improves the draft in your fireplace. A better draft enhances how well your logs burn, increasing efficiency. When fires burn longer and at higher temperatures, you’ll reduce your heating costs during the winter.
A well-insulated chimney liner reduces the chance that high heat inside the flue will overheat the surrounding bricks, which can disintegrate under extreme temperatures. It also prevents timbers in your roof and attic from absorbing high heat, reducing the risk of fire in your roof or attic shingles.
You wear a coat in winter to keep warm air in and cold air out. The same concept applies to insulating your chimney liner. An insulated liner maintains the high temperature of gases rising from your fireplace. Why is this important? As gases cool, they condense as they ascend the flue, leading to a buildup of creosote—a flammable mixture of chemical compounds. If you burn logs that aren’t properly seasoned, the creosote from condensation can significantly increase the risk of a chimney fire.
