FlexLine Flexible flue liner

After forty years of lining chimneys, this is the flex of our choice.

Over the years we have lined hundreds of chimneys and supplied literally miles of flexible liner. This has given us the opportunity to see how the different makes of liner stand up to the stresses and strains of being pulled down a chimney and how the flexible flue liner reacts to being subjected to continuous high temperatures with occasional bursts of very high heat. It also gives us the opportunity to see how the flexible flue liner puts up with being in a damp chimney and how it copes when unseasoned, tar filled wood or high output cokes and coal are burnt. We have subjected the various chimney liners to other tests as well, such as how quickly will the inner skin of the flexible liner crease when the liner is curved, thus compromising its integrity (and you won't see that from the outside of the liner).

The liner fittings that we use are made of decent thickness stainless steel and well designed. 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 guaranteed 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.

We have total confidence in the quality of our liners which is why we're happy to give both the 316 and 904 grade liner a lifetime warranty.
