About Flexible Flue Liners

Flexible flue liners are used to contain fumes and other burning materials. They are ideally installed to wood burning and multi fuel stove chimneys.

Our flexible flue liners are divided into two:

Standard Grade 316 Stainless Steel Flexible Flue Liner

 Suitable for most domestic wood burning stove applications, it affords premier heat protection and a long lifespan. In fact, it can last for more than 10 years.

The products available under the Standard Grade 316 Flue Liner include:

All of these flexible multi-fuel flue liners are Class 1 and are engineered using 316L stainless steel. They have been made according to the British and European standards – EN 1856 – 2 T450.


Premium Grade 904 Stainless Steel Flexible Flue Liner

Recommended for 'slumbering' stoves (i.e. stoves that are kept overnight), this flue liner is made of a higher quality stainless steel than the 316 flue liner. It can last for more than 15 years.

The products available under the Premium Grade 904 Flue Liner include:

These flexible multi-fuel flue liners are Class 1 and are engineered using 904 stainless steel, following the British and European standards – EN 1856 – 2 T450.

Note: Stove manufacturers recommend fitting a multi liner when installing a stove. Fluebay specialises in flue liners that are suitable for multi-fuel burning (such as coal, peat, dry logs), as well as oil and gas.


What does a Flue Liner actually do?

  • It provides a better ‘pull’ which helps to push the smoke out of your house/establishment
  • It enhances the performance of your stove to make it more controllable
  • Liners push the heat up the chimney to prevent fire hazards


Advantages of using a Flexible Flue Liner

  • Compared to other flues, they are more proficient at protecting chimneys from damage caused by condensates and tars
  • They provide good insulation properties
  • They provide better protection for decoration on the chimney breast


Bespoke Flexible Flue Liners

Fluebay also manufactures stainless steel twin walled flexible flue liner from 100mm (for condensing oil boilers) to 300mm. We can supply you with pre-cut lengths of flue liner (usually 6m for Bungalows or 9m for Two Storey houses) or specific lengths for those with particular requirements.
