The liners of Supreme Fireplaces are made of high quality stainless steel. They can be installed inside a masonry chimney or used to repair a wood burning, gas or oil chimney.



  • Increases the safety of your chimney. Approved to the standard ULCS-635-M90.
  • Increases the efficiency of a slow wood-burning appliance.
  • Installation is fast and affordable.


Features and Benefits:

  • High quality stainless steel of type 316
  • Our liners contain titanium which resists better to heat. This also reduces the risk of the liner getting perforated by a sharp object.
  • The thickness of our stainless steel liner is 5000 of an inch. Most manufacturers use 3000 of an inch, which is almost half the material and thickness of our liner.
  • Our flexible liners are designed with 10 grooves and an interlocking system of 7 folds providing a greater seal.
  • The flashing is fabricated with an airtight joint making the edges smooth and safer to manipulate.
  • Easy to connect to the rain cap
  • Fast and easy installation
  • The tee is an airtight assembled piece that facilitates the chimney sweeping.

Flexible liners are easy to install.
