Material Matters
Look for 316 stainless steel or 316L stainless steel for durability and heat resistance. These materials provide strong protection against corrosion and heat damage. Aluminum may be lighter, but it is less durable. Sticking with stainless steel is a solid choice for longer-lasting performance.

Special Features
Many chimney liners include features like quick connect and warranties. Warranties, especially transferable ones, add value. Quick connect options make installation faster and easier. Look for these features when comparing different liners.
