What is a Flexible Chimney Liner?

A flexible chimney liner is just like a dryer vent hose, but a lot beefier. The flexibility of this chimney liner allows for the homeowner or chimney sweep to maneuver the chimney liner down a chimney that might have bends or imperfections in the bricks or masonry work. If your chimney has a straight flue right to the fireplace or fireplace insert, then you will want to use a rigid chimney liner.

You can still use a flexible chimney liner if you have a straight flue, it is just your choice.  A lot of flexible chimney liners are made of  316L which is the standard for a lot of chimney liner manufacturers.

This chimney liner alloy is a stainless steel which means that it is very resistant to rust and other forms of corrosion. The other type of flexible chimney liner on the market today is made of 316Ti which is stronger at higher temperatures and is overall more durable then a chimney liner made of 304L or 316L. The only double wall chimney liner on the market that is made from 316Ti is the Flex King Pro chimney liner. Flex King is also made from 316Ti.

What Can I Hook Up to My Flexible Chimney Liner?

With any chimney liner you can hook up most heating appliances that vent out through your masonry chimney.  Depending on the connection that your heating appliance has to a chimney, you will need either a tee connector or an appliance connector.  Here at Chimney Liner Express we offer flexible chimney liner kits that contain everything you will need to hook up your chimney liner to your heating source.

What Should I Look For In A Flexible Chimney Liner?

When shopping around for a flexible chimney liner, there are a couple things you want to be sure you have when you are buying a flexible chimney liner for your home.  First is making sure that your flexible chimney liner comes with a lifetime warranty. Some companies offer flexible chimney liners, but their warranty only covers installation or a limited time. Also be sure to know what the warranty encompasses and how it becomes void. The second thing to look for is being sure that your flexible chimney liner is UL listed. This will make sure that your flexible chimney liner can meet the extreme temperatures and wear that you will be putting on it. Underwriters Laboratories puts products through very tough physical tests before they put there name behind the product or brand. That means when you see that UL seal, you are getting the best product on the market.
