Features of a Schiedel ICS Chimney System

Schiedel’s Insulated Chimney System (ICS) has been designed and manufactured with innovative technology, creating an advanced corrosion resistant design. As the only stainless-steel system to have passed the internationally recognised GASTEC corrosion test, this Schiedel twin wall flue system has revolutionised the construction of twin wall chimneys. Due to the unique assembly method of this metal chimney system, the inner liner is able to expand and contract with the temperature, improving the flue draught and minimising condensation. Moreover, the assembly allows the flue to withstand the temperatures of an internal soot fire, prioritising safety within the design.

From the simple push-fit jointing system to the Superwool blanket for maintaining flue gas temperature, every feature in the Insulated Chimney System (ICS) works to improve the overall function of the chimney.
