The multifuel chimney flexible flue liner is compatible with a variety of wood, coal, gas and oil burning appliances.

Inside the chimney flexible flue liner

The robust spirally wound double-skin construction of each Multiflex flexible flue liner adds straight to the joints, enabling the chimney flue liner to withstand high pressure. The Multiflex chimney liner interior has been designed to enable the smooth and efficient passage of flue gases, while the flexible flue liner exterior maintains optimal flexibility thanks to its durable corrugated construction.

There are two Multiflex flexible flue liner grades, 316L & 904L grades of stainless steel, for use with wood or multifuel solid fuel burning stoves, open fires or boilers. Each chimney flue liner is CE marked and approved by HETAS.
