What Are Chimney Flue Liners?

Chimney Liner Repair & ReplacementA chimney liner, or flue liner, basically forms a barrier between what’s coming out of your firebox, furnace or stove, and the actual structural components of this passageway. This barrier can be made of fire-clay flue tile, stainless steel, or aluminum, depending on the type of system it’s venting. The inner layer runs through the inside of a chimney and contains all the products of combustion until they exit the home. It must be maintained or smoke, heat, and CO will enter the airspace of your chimney and walls causing serious safety concerns, including carbon monoxide poisoning and fire beyond the designated fire walls.

Three Main Functions of a Chimney Liner

  • They protect the home from heat transferring through to combustibles. Inadequately lined chimneys allow gasses and heat to pass into walls and living spaces which can cause extensive property damage and fires.
  • They keep the masonry safe from the corrosive byproducts and humidity of combustion. The gasses are very acidic and high in water vapor content. When the gasses aren’t venting correctly, they cool and condense into acidic water which will eat away at the mortar joints from the inside of the chimney out. As the joints disintegrate, heat transfers quickly to the nearby combustibles and dangerous gasses, such as carbon monoxide, can leak into various areas of the house.
  • Lining your chimney correctly provides the right size flue for maximum efficiency of appliances. Today’s wood stoves, and gas or oil furnaces, require a correctly sized flue to function properly. It is the role of the chimney system to provide a safe passage for the products of combustion to escape. An improperly sized flue can lead to substantial creosote buildup in fireplaces and wood-burning stoves, and produce crippling amounts of structural damage due to condensation with natural gas appliances.

Let’s Clear The Air

Nobody wants to breathe smoke or deadly carbon monoxide fumes. A damaged chimney lining can invite these dangerous and combustible vapors into your attics, walls, and ceilings instead of containing them safely until they exit the building. This puts you in danger and increases your likelihood of a house fire.

Signs You Have A Flue Liner Problem

Since the lining is on the inside, it can be hard for anyone besides a certified technician to find and correctly diagnose a problem. Drafts, smoke, unpleasant smells, and visible outer structure deterioration can all be signs of needed flue repairs.
