This type of venting system, often available at major home improvement retailers, is designed for safely exhausting combustion byproducts from wood-burning stoves and other solid-fuel appliances. It features a dual-layer construction, typically with an inner stainless steel pipe surrounded by an outer layer of galvanized steel, separated by an insulating air space. An example includes a six-inch diameter section used to connect a wood stove to a chimney system.
The importance of this system lies in its ability to reduce the risk of fire hazards associated with high flue temperatures. The double-wall design minimizes heat transfer to surrounding combustible materials, thus lowering the clearance requirements compared to single-wall options. Historically, advancements in stove pipe technology have focused on improving safety and efficiency, with dual-wall systems representing a significant step in reducing the potential for chimney fires.
