The importance of chimney lining:
Chimney lining is one of the most vital part of the chimney. It is actually the part of the chimney that protects the chimney from either getting caught on fire, or from overheating. Two of the most popular materials used for the lining of the chimney are stainless steel and aluminum. Although, stainless steel and metal do last for long, but with time water and sulfur inside the chimney mix and as a result, the mixture starts corroding the liner which results in the liner peeling away from the walls as well as from the frame of the chimney. It is for these reason that chimney relining is actually important.
Thehistory of the chimney lining:
Clay tiles were used to be of the highest quality before the twentieth century and the chimneys used to be lined with mortar. However, throughout the period of the 1980s, the NBS – National Bureau of Standard tested out the masonry chimneys. It was found out that the chimneys without the lining would be completely dangerous for use.
Why you need chimney relining:
If the lining of your chimney liner is sized properly, then the air control in your chimney will be proper and will not cause any fire. However, if the liner is sized incorrectly then it can cause an excessive buildup of creosote in your chimney. NBS conducted a number of tests which proved that the flue gases that enter the mortar and the brick decrease the lifetime of a particular chimney. This might cause the poisonous gases to leak inside the house which will put your family at risk.
Types of chimney liners:
There are basically three types of liners for the chimney, all of them designed for a specific type of chimney.
- Cast in place liners:
Such a liner has the ability of creating a sleek and seamless interior which is quite easy to manage and take care of. It also reinforces a weakened and a worn structure of the chimney. Such a type of liner is the best if a chimney has a number of different flues in it.
- Clay tile liners:
Such liners are readily available, are inexpensive and work the best with a chimney installed in an open fireplace. There is one disadvantage to this liner and it is that it does not absorb and distribute the heat quickly so the heating is quite uneven. This causes the liner to crack eventually and gradually split apart which hence results in a replacement much earlier.
- Metal chimney liners:
Such liners are mostly made out of aluminum or stainless steel. The basic use of such liners is for the upgrade and the repair of chimneys that already exist. Such liners have been ranked quite high in context of the durability and the safety. These liners are used often when liners are replaced. The chimney liners made out of stainless steel work the best with oil or gas applications
