Question

What materials are chimney liners made of?

Answer 1

Chimney liners can be steel or stainless steel if the heat is intensive. Hi efficiency gas furnaces normally use flexible steel and oil burning funnaces generally require stainless. It all depends on the local building codes.

Answer 2

Chimney liners are most often made from series 304 or 316 stainless steel. It is typically non magnetic.

Rigid pipe generally comes in sections. The sections are round and one to two feet long.

They can also be five to ten inches across the diameter.

This is very different from flexible liners. The thickness gauge of these sections is usually 24 or 22 gauge stainless.
