Why Does Your Chimney Need a Liner?
You need to have a chimney liner because it lessens the risk of chimney fires, protects chimney masonry, prevents toxic byproducts from leaking indoors, and reduces soot and creosote build-up. Let us learn more about the importance of having a chimney liner below.
Lessens the Risk of Chimney Fires
One of the reasons why you need to have a chimney liner is that it lessens the risk of chimney fires. The chimney is made from materials that will not catch fire. However, you need to consider the support structure as well as other combustible frames near the chimney that cause a fire. Accidental chimney fires can be prevented when you use chimney liners because they limit heat transfer.
Take note that woodwork as well as other combustible material near the chimney can catch fire from the flame and heat that passes through the chimney. Hence, you should install a chimney liner. Moreover, you also need to have your chimney inspected regularly.
Protects Chimney Masonry
Another reason why you need to install a liner for your chimney is that it protects the masonry of the chimney. Chimneys are made from strong materials such as bricks. However, bear in mind that bricks are still porous. When the fireplace is lit, it creates combustion that produces corrosive byproducts.
With the frequent use of the chimney, corrosion can happen and the masonry is damaged. The chimney liner protects the masonry. If the masonry gets damaged, dangerous problems such as carbon monoxide poisoning can occur.
Prevents Toxic Byproducts from Leaking Indoors
Installing a chimney liner can prevent toxic byproducts from leaking indoors. The fireplace can provide warmth to create a comfortable temperature inside the house, but it can also produce toxic gases like carbon monoxide. Any kind of toxic byproducts must be exhausted outside your home. Without a chimney liner, there is a high chance for toxic gases to leak indoors which can cause health issues. Bear in mind that severe carbon monoxide poisoning is fatal.
Minimizes Buildup of Soot and Creosote
Another reason why you must install a chimney liner is that it minimizes the buildup of soot and creosote inside the chimney. Soot and creosote can accumulate inside the chimney and without a liner, they can cause a fire. Aside from that soot and creosote are also hard to clean because they seep into the mortar and joints of the chimney. Installing a liner will help protect the chimney and also make it easier to clean and maintain.
