Chimney liners are perhaps one of the most overlooked aspects of the fireplace. They play a valuable role, though, by creating a barrier between the chimney wall and flue. This insulates the interior and prevents overheating. There are various types of chimney liners, each with their pros and cons. A chimney repair service can determine the best one for your particular type of fireplace.
Clay Tile Chimney Liners
Clay tiles are a traditional favorite due to their resistance to heat and corrosive byproducts. They also have a projected lifespan of about 50 years. However, clay tiles are not as effective for venting smoke due to the liners being square or rectangular shaped. Smoke dissipates best when exiting through a spherical structure.
Cast-in-Place Chimney Liners
Cast-in-place liners are made using poured-in cement. This method is normally used for chimneys with damaged masonry where a clay tile liner is not feasible without dismantling the entire structure. This type of liner holds all the same benefits as clay tiles. In addition, they’re also highly resistant to corrosive elements like condensation and acid. Such liners, unfortunately, can also be pricey. This is specially the case if the existing clay flues need to be removed, which means more labor.
Metal Flue Chimney Liners
Metal liners are the type we recommend and generally provide for Seattle homeowners. For one, they’re readily available for fireplaces and heating appliances of various shapes and sizes. They’re also the most affordable option due to their relative ease of installation. Parts and labor included, these liners run, give or take, about $100 per foot. Lastly, metal is less susceptible to creosote buildup due to their corrugated surface. This makes chimney cleaning by a professional easier.
