Different Types of Liner – Focus on Stainless Steel

Stainless Steel Chimney & Flue Liners

Having established that your chimney or flue needs to be lined the next question is – which type of liner do I go for? If you are looking for chimney lining in Oxford then call Turner Baker today.

There are many different types of liner on the market made with lots of alternative materials.  The main differences between the liners can be simplified into three variables – durability, longevity and price.

The entry point into chimney and flue linings is stainless steel.  There are lots of different grades and ratings of stainless steel, but as a rule of thumb, the thicker the liner the better.

Stainless steel can be available in either a flexible format (to accommodate bends in the chimney or flue) or as a rigid piece. Flexible stainless steel liners  are supplied as one long piece whereas rigid stainless steel is supplied in sections which are slotted together.

 

Flexible Stainless Steel Flue Liners

Flexible stainless steel flue liners are available from Turner Baker Ltd for either multi fuel stoves or for gas and oil appliances.

Multi-Fuel flue liners (Class 1) are available in two basic grades of stainless steel. The standard product is Grade 316 which comes with a 10 year product guarantee, and the higher quality grade 904L comes with a 20 year product guarantee.Chimney Lining Company Oxford

The corrugated outer wall provides crush protection during installation. The inner wall is smooth to encourage the flow of flue gasses and to discourage the build up of soot and other potentially corrosive residue.

Gas and oil flexible flue liners (Class 2) however are manufactured out of a single strip 316 grade stainless steel and are designed for atmospheric gas and kerosene appliances where the flue gas temperature does not exceed 260°C. These liners are not suitable for use with solid fuel.

Flexible flue liners are available in a comprehensive range of diameters suiting all applications, from 100mm to 350mm.

Twin Wall Rigid Stainless Steel Flue Systems

 

Twin Wall Flue Systems are modular insulated flue and chimney systems that can be used either internally or externally. Turner Baker Ltd can supply systems for a range of applications:

  • High and low temperature applications
  • Positive and negative pressureChimney Lining Experts Oxford
  • Condensing appliances.
  • Solid Fuel, including Biomass
  • Gas and Oil Appliances

The liner units are constructed using a stainless steel inner liner, with at least 25mm of insulation, surrounded by a structural outer skin. Units are retained in place using locking bands and braced to adjoining structures with wall bands. The flue can then be constructed either externally or internally through the property or building, or can be free standing.

Turner Baker Ltd are able either to supply and install stainless steel flue products or, in consultation with the client, put together a full flue kit for self installation.
