FlexLine Flexible flue liner

After over forty years of lining chimneys, this is the flexible flue liner of our choice. So confident are we of the strength of our liners that we back them all with a lifetime guarantee.*

Over the years we have lined hundreds of chimneys and supplied literally miles of flexible flue liner. This has given us the opportunity to see how the different makes of liner stand up to the stresses and strains of both everyday use and on those times when things get way too hot.

The flue liner fittings that we use are well designed and made of decent thickness stainless steel. The design of the flex pipe adaptor, for instance, ensures that even if damp wood is burnt, potentially leading to an excess water/tar mix running back down the flexible chimney liner, it will end up back in the stove, with no chance of it spilling over from the fitting. The same can't be said with many of the cheaper alternatives.

As well as the standard 316 grade stainless steel chimney liner that is used in most domestic applications we can also supply 904/904 grade stainless steel chimney liner. This is normally used in situations where the liner will be subjected to very high temperatures or heavy condensate formation. 904/904 means that both the inner and outer skin are made of 904 grade stainless steel and makes it the most resilient liner available. Many of our competitors supply 904 liner which actually has a 904 grade inner but a 316 grade outer.

*guaranteed for the lifetime of the appliance to which it is connected.
