Pros and Cons of 3 Different Types of Chimney Liners

Share

Clay, metal, and cement are the three most common types of chimney liner. Each type of liner presents its own advantages and disadvantages. So, like every other part of homeownership, you have a decision to make when you need flue repair or replacement. Here are the different types of flue and a few pros and cons for each.

  • Clay Tile: Clay is the most common type of chimney liner. They’re readily available, inexpensive, and work very well for chimneys that are well-maintained on a regular basis. They cannot, however absorb and evenly distribute the heat that occurs during a chimney fire. Chimney fires are caused by creosote, so regular maintenance can help prevent them. Clay tiles also do not contain liquid combustion byproducts produced by most modern gas appliances.
  • Metal: Stainless steel and aluminum are often used successfully as chimney liners. They’re very safe and durable as long as they are properly maintained. Stainless steel is good for most heat producing appliances where aluminum should only be used for medium efficiency gas appliances. High temperature insulation should always be used with metal chimney liners to protect your home’s combustible frame from excessive heat. Metal liners are more expensive than clay.
  • Cast-in-Place: This type of liner is a permanent installation to your chimney. They are literally a lightweight cement that is poured on site and – cast in place – to create a smooth, seamless, insulated passageway for smoke and gases. They can strengthen the structural integrity of the chimney and they are suitable for all types of combustion. They are more expensive than the other two options.

What the Chimney Liner Does

The chimney liner serves three purposes. They protect combustibles in the home from heat transfer. They protect the masonry from combustion’s corrosive byproducts. And they increase the efficiency of the appliance to which they serve. The increased efficiency is generally the primary focus because your chimney’s primary job is to facilitate the removal dangerous gases from your home.

A damaged flue compromises the chimney’s ability to successfully remove gases produced by the fireplace or other wood burning appliance. This puts your household at risk for carbon monoxide poisoning. It’s always better to be safe than sorry where your family’s health is concerned.
