Is your chimney liner still doing its job? If you’re not sure, it might be time to take a closer look. A damaged or worn-out chimney liner can lead to serious safety risks, including chimney fires and carbon monoxide leaks. In this guide, we’ll cover the top signs your chimney liner needs replacing - and what can happen if you don’t.

Flexible chimney flue liner for lining chimney stacks where no clay, terracotta or concrete lining exists. Constructed with two layers of stainless steel, available in 316/316 and 904/904 grade, these chimney liners increase the efficiency of the chimney to extract combustion gases and carbon monoxide from your stove, fireplace, or appliance.

Distinguishing between 316 and 904 flue liners lies in the composition of their stainless-steel layers. Stainless steel, a blend of iron ore, silicon, nickel, chromium, molybdenum, and carbon, yields a corrosion-resistant steel variant. Varying the exact proportions of these elements alters the steel's properties, influencing factors like corrosion resistance, hardness, and malleability, resulting in different grades.

The 904 grade boasts enhanced resistance to corrosive chemicals compared to the 316 grade, particularly with acidic residues from fuel combustion
