Rigid chimney liner is an excellent way to line a chimney. Rigid chimney liner is thicker and will clean much better than corrugated flexible liner. The only problem with rigid liner is that if you are relining a chimney that is not perfectly straight its next to impossible to put the liner in. Most chimneys on not-so-new homes are not straight. Most older homes have chimneys with offsets especially if they go through the center of the home.
If you have a straight chimney you might want to look into rigid chimney liner.
The season is fast approaching when our chimneys will be put to the test yet again. If you are like most people you have probably put off cleaning your chimney after last years usage. A lot of people don’t fully understand why a clean chimney is a safe chimney. Wood burning stoves make a mess out of chimneys. If unseasoned wood is burned creosote will build up very quickly.
Another factor for quick creosote build-up is burning wood too slowly. The chore of putting more wood on the stove is one that many of us don’t like. If we don’t have kids to carry in the wood, it may just be easier to prolong the life of the wood in the stove by keeping the dampers closed down. Doing this for lengths of time will without a doubt create lots of creosote in the chimney.
Make sure to have your chimney cleaned before you start using it this year. It’s just about Fall and chilly rainy days are coming. Make sure your chimney is safe before you light up your stoves.
Chimney Liner Depot is now offering an instructional dvd showing how to install a flexible chimney liner. Here are some quick clips from the video.
Flexible Chimney Liner
The easiest and most cost effective way to repair a chimney is to reline it with a flexible chimney liner.
When chimneys get old or are not maintained properly they can deteriorate and create hazardous conditions. Cracked tiles and deteriorating masonry can allow hazardous gases or even fire to enter your house. In order to remedy these situations there are two things that can be done. The entire existing chimney can be torn down and rebuilt, or you can reline the chimney with a stainless steel or aluminum flexible chimney liner insert.
What is a flexible chimney liner?
A flexible chimney liner is just that, flexible, as opposed to rigid. The wall thickness ranges from .005 in. to .019 in. All stainless steel liners have some form of ribbed construction and are supplied in continuous lengths. Flexible liners allow for both top and bottom support because any expansion due to heating is absorbed by the liners flexible ribbing. Some flexible liners can be bent by hand while others are less flexible and require special tools for bending. The use of rain caps are recommended.
