Your Chimney Needs a Liner and Here is Why
A Chimney is vertical in shape to ensure the smooth flow of the gasses to the atmosphere and the space inside the chimney through which the air passes is called the flu.
The chimney liner is made from hollow rectangular and circular hard burnt clay which contains the combustion products inside the chimney and directing them to the atmosphere outside while protecting the inside of the walls of the chimney.
Functions of a chimney liner
Helps to protect the house from heat transfer to inflammable substances; when the chimney is not lined, it could easily allow heat to travel out of the chimney rapidly to the nearby items like woodworks and catch fire in a brief time.
The flue gasses are dangerous and acidic eroding the mortar and if allowed to penetrate the walls of the chimney are likely to reduce its lifespan.
Lining the inside of the chimney ensures that no excessive creosote build- up occurs in the burning stoves which could lead to the production of more dangerous gases carbon monoxide.
Variety of chimney liners
Clay Tiles; these are the most common type of masonry chimney liners and have been a traditional favorite for lining chimneys existing in most old homes because of their well-finished mortar joints.
Cast in place liners; these are lightweight products that look like cement and were created around 60 years ago with an insulation character which keeps heat from leaving the chimney hence fully consuming the by-products of combustion.
When the metal chimney liners are well installed and maintained they become very durable as the aluminum is effective for gas appliances only while the stainless steel will serve both oil, wood and gas applications.
Considerations to make before getting a chimney liner
Most people install chimney liners because it will ensure optimal performance of appliances in the house and it is safe to do so.
It is important to get to know what the chimney professional will have to do when fitting the chimney liner to ensure maximum effectiveness, especially for stainless steel liners.
It is important to decide with the aid of the chimney professional which type to install and what will work best in your circumstance and environment as well.
Consider how the chimney liner will affect the ventilation process; a chimney liner which is well sized for the fireplace or a stove should be able to maintain or make better the venting process because a smaller or larger coating will adversely affect the operation.
Consider the warranty; a majority of the chimney liner warranties require that the installation is done correctly by a qualified professional and inspection did regularly.
