Rigid chimney liner is the best chimney liner you can use. The only thing is you must have a straight masonry chimney flue. If your chimney flue is not straight and has offsets, installing a rigid chimney liner is not your best bet. Most likely you will not be able to install this type of chimney liner. If your chimney has offsets then you will need to use a flexible chimney liner.
Rigid chimney liner is smooth like glass. This will make it so creosote will not stick to the sides of the chimney liner like traditional corrugated flexible chimney liner. Chimney Liner Depot has the best rigid chimney liner available. Give us a call and we will help you figure out if rigid chimney liner will work for your chimney relining project.
