These chimney liners will fit inside of your chimney and it is up to you to make sure that they are fitted all the way along the inside to the top of the chimney and that they are well covered.

Chimney liners have many different purposes and are highly important chimney supplies. The purpose of this is to provide you with lining to contain the combustible products heading through your chimney and helping to encourage them to flow outside thereby making it safer. At the same time they are designed to protect the walls of your chimney from the heat and corrosion that would otherwise occur. They also prevent the smell of smoke and other fumes from lingering in your chimney and help to insulate the chimney itself and prevent too much cold air from getting in and altering the temperature of your property.

For this reason your chimney liner is a good investment and will save you a lot of money in repairing your chimney potentially and in expensive heating costs.
