4 Advantages of Using a Flexible Chimney Liner

Although some people are reluctant to use flexible chimney liner in their homes because its corrugated surface is often difficult to clean, this type of chimney liner actually has more advantages than disadvantages. Not only is this type of liner easy to install, it is also safer compared to other types of chimney liners. Below are four advantages of using flexible chimney liner.

1. Easy to Install

If your chimney is more that 10 feet high and it bends in some places, you should get flexible liners for your chimney. Long lengths and curves can spell a lot of problems for rigid chimney liners. On the other hand, fitting an assembled flexible liner inside your chimney is not exactly a walk in the park but it is definitely easier than trying to fit a rigid liner inside your 12 feet chimney.  

Installing the flexible liner into your chimney can easily be done with the help of a partner. To do this, tie the top of the assembled flexible chimney liner with a rope and ask your partner to pull the rope from the crown of your chimney while you guide the liner into place. Once the liner is in place, apply silicon caulk around the crown of the chimney then use your hands or a flat surfaced wood to press the top of liner into the silicon caulk. After securing the top of the liner, secure the bottom of the liner and then connect it to the appliance connectors.

2. Less Prone to Breaks and Tears

Unlike rigid chimney liners that remain constant despite being exposed to varying degrees of heat, flexible chimney liners expand and contract when exposed to different temperature levels. Flexible chimney liners adapt easily to changing conditions so they are less likely to tear or break. As it is, flexible chimney liner is more efficient in venting out dangerous gas out of your home. According to studies, leaking chimney liners have been blamed for so many cases of carbon monoxide poisoning in the United States in the last several years. Carbon monoxide is a chemical byproduct of burning wood and using fossil fuel to power your stove. If your chimney liner has holes or leaks in it, it cannot vent carbon monoxide efficient and some of the gas can seep back inside your house and cause health hazards.  

3. Less Prone to Creosote Build-up

Creosote is natural byproduct of burning wood and it often builds up on chimney walls. Since creosote is highly flammable, chimneys that have thick creosote build-ups are prone to fire. Chimneys with flexible liners however are less prone to creosote build up. When the flexible liner contract and expand, the creosote on its surface loosens up and falls away.

4. Costs Less

In terms of prices, a flexible chimney liner is cheaper compared to rigid chimney liner. Moreover, since this type of chimney liner is relatively easy to install, you do not need to pay a professional to do the installation job for you.
