Let’s define what a lining system is first. Masonry chimneys have an inner liner of clay flue tiles. The liner keeps the heat of flue gases inside the chimney. Now the chimney can’t overheat the nearby combustibles, such as the framing and walls of your house, and possibly start a fire. The liner is also important because it keeps carbon monoxide, moisture, smoke, creosote, and other products of combustion from leaking through the bricks and mortar of your chimney and additionally into your home.
Let’s talk about Relining. It’s Simple. If a liner was never installed or there are problems with the current liner (tile lining cracks, crumbles or has deteriorates over time). Often times water damage, chimney fires, or just age can cause the deterioration of your clay liner. National Fire Prevention Association (NFPA) code 211 says it must be replaced. The most popular, effective and economical way to reline your chimney is with UL listed, stainless steel relining pipe. As you can see, a secure lining system is crucial to the safety and well being of your home and family.
