What is a class A chimney?

A Class A chimney is a type of venting system designed for high-temperature applications, specifically for wood stoves, fireplaces, and other solid fuel-burning appliances. It consists of a double or triple-walled construction that provides insulation, allowing it to safely handle flue gases and prevent heat transfer to surrounding structures. Class A chimneys are typically made from stainless steel or other durable materials to resist corrosion and ensure longevity. They are essential for maintaining safety and efficiency in venting combustion byproducts.
