Chimney Liner Question
Easy Flex:
The Chimney Champion Easy-Flex liner is used in over 85% of chimney reline projects today. It is chosen by most professionals and home owners due to its light weight and installation ease. Don’t let the word “Light” or “Easy” fool you, this liner boasts the same Lifetime Warranty as the Heavy-Flex and Rigid Liners do. Unlike most other light-weight liners, the Chimney Champion Liner is 100% UL Listed and approved in both the USA and ULC approved for Canada. The Chimney Champion Easy-Flex is .006 thick making it the perfect combination of strength and durability yet maintaining its light flexible properties. It is recommended for all fuel types and can be made in 4 varying size shapes. No wonder the Chimney Champion Easy-Flex Liner is our No.1 customer choice liner selected by both Professionals and homeowners alike.
Chimney Liner Question
Heavy Flex:
The Chimney Champion Heavy-Flex Liner is built to last the most extreme harsh conditions of solid fuel burning such as wood or coal. It can withstand a rigorus cleaning with even the toughest wire brush. Although this Liner is Flexible, it is recommended for mostly straight chimneys and the components for this liner must be screwed or riveted together. Unlike the Easy-Flex liner the inside walls of the Heavy-Flex liner is smooth making it more difficult for creosote to build up inside. As mentioned before this liner is extremely heavy and would require help and in some cases the use of a “lift” to lower the liner into the chimney or a top-mounted winch to pull the liner up the chimney. The Heavy-Flex liner also is 100% UL approved for both the USA and ULC approved for Canada. And like the Easy-Flex is available in 4 varying size shapes.
Chimney Liner Question
Rigid Liner:
The Rigid Liner has the smoothest inside walls making it the most difficult for creosote to adhere to. The Rigid Liner will withstand the harshest conditions of solid fuel burning as well as withstanding rigorous cleaning from a stiff wire brush. Rigid liner must be assembled in sections as it is lowered into the chimney, making this selection best for straight and preferably short chimney runs.

Chimney Liner Question
304L-alloy is great for wood burning applications by doing a great job preventing corrosion in wood burning environments. Not to be confused with basic 304, 304L is a low-carbon stainless steel. 304L is significantly different from basic 304, as it is much more resilient to corrosives and rust. Making this an excellent choice for solid fuels such as wood or wood pellets.

Chimney Liner Question
316L-alloy has more molybdeenum and nickel and slightly less chromium than 304-alloy. The result of these slight differences is that 316 stainless steel is substantially more resistant to corrosion.  Taking this one level further, 316L is processed as a low-carbon alloy making it more resistant to corrosion than basic 316. 316L is an excellent alloy for coal, oil, and noncondensing or lower efficiency gas appliances.

Chimney Liner Question
316 Ti-alloy adds both molybdenum and titanium to 304-alloy, giving excellent corrosion resistance in acidic environments and high heat corrosion resistance. This corrosion resistant stainless steel alloy takes it up another notch making it a great choice for wood, coal, oil, and noncondensing gas.

Chimney Liner Question
AL 29-4C alloy, the most corrosion resistant of all alloys, It is a superferritic stainless steel designed by Allegheny Ludlum  in the  early 1980s.  It is good for all gas appliances, especially higher efficiency high-condensing appliances.  With it's superferritic properties it the best choice for combating the high acidic bi-product of burning corn. With the lower temperatures of burning corn and high-efficiency gas furnaces this is the best choice, however it is not as good as 316 Ti in high temperature environments.
