Chimney Flue 4"

Our flexible flue liner is Hetas and CE approved, Suitable for use with solid fuel, wood, gas and oil appliances.

  • 316L grade - for all applications except processed coal.
  • 904L grade - even more resistant to the corrosive substances created by combustion. Also for processed coal and condensing applications.

A flexible liner is easy to handle, with high resistance to traction and torsion. With specific fittings a chimney liner is quick and easy to install.

If your flue liner is not long enough for your installation there will undoubtedly be delays and disappointment (plus the additional cost of a correctly sized flue liner). Adding an extra metre (or two) - will help ensure your installation goes ahead without delay.

The flue liner legally needs to be a minimum of 6" in diameter if you are burning wood. Unless when you install a DEFRA approved stove with a 5" flue outlet, in which case you can use a 5" liner.
