SWKZ - heat resistant chimney liners

Chimney liners dedicated to protect chimney ducts exhausting fumes from woodburning stoves


Heat resistant chimney liner system are single-walled chimney liners and ducts, made of heat resistant chrome-nickel steel sheet (type 1.4828 according to DIN 17441). They protect the inner surfaces of ceramic chimneys (exhausting fumes from wood burning stoves), from the destructive functioning of temperature and acids. These chimney liners can withstand high temperatures that can occur in woodburning appliances.
