Twin wall flue

Clearline Twin Wall Flue is a stainless steel insulated flue system designed for solid fuels, oil and gas and we consider it to be the best prefabricated insulated flue system on the market. It comes as either AKW, for 125mm and 150mm flue systems, or AKC, which covers 175mm and 200mm diameters.

Clearline has been designed by people who install flues every day and this is reflected in the ease with which it goes together, its comprehensive list of components and its neat, clean-lined look once it is in place. 

Clearline has been tested at a working temperature of 600℃, which is 150 degrees higher than most systems, as well as passing soot fire tests at 1000℃, all to ensure that it is completely safe in any environment.

As well as being one of the best looking and safest systems on the market, Clearline twin wall flue is also exceptionally good value for money.

Our flue experts are here to help and will guide you through exactly what you need to get your stove installed quickly, safely and without breaking the budget.
