Chimney liners serve several purposes. Not only do they protect the house from heat transfer to combustibles, they protect the masonry from the bi-products of combustion that can cause corrosion.
Many chimneys lined with clay liners and mortar do not allow for long lasting use. Any cracks in the tile, gaps in the mortar joints or fallen out mortar can result in serious problems to the functionality and safety of your chimney. The allowance of smoke and embers making their way through your liner could result in a fire. This can also cause draft problems and the possibility of a smoky smell in your home. Using a stainless steel flex liner eliminates the problems that can come from a traditional clay liner flue.
