❖ Why fit Dura Flue? ❖

Dura Flue is the only chimney liner in the UK that is manufactured in such a way that it does not come apart internally whenever flexed and or installed. It's the only chimney liner currently on the market which is manufactured so that the internal duct is completely sealed ( you can see from the pictures the difference ) If the flue liner you’re considering to purchase has to be fitted a certain way up ( it will have directional arrows on it ) then it is not Dura Flue. Dura flue can be fitted either way up because it’s completely sealed on the inside so whichever way it is fitted you’ll be safe to know it’s fitted correctly. 

      Dura flue is also designed with 2 completely different patented types of stainless steel strips, inner and outer. You may hear other suppliers using terms such as a better quality steel or fit the best but with no technical explanation. We use the same 316 or 904 grade stainless steel to manufacture our flue liners but its the process in which the steel goes through that makes them unique and able to withstand higher levels of corrosion. It also gives them their unique durability & strength. The outer strip, is profiled into a hard corrugated shell, so when the liner is being dragged down a brick chimney, it's protecting the inner smooth duct. With a standard chimney liner - this is where the inner duct can be damaged on installation and so the internal flaps may come apart (refer to picture). This doesn’t happen with Dura Flue. The corrugated outer skin can take the punishment of installation leaving the inside nice and smooth.

The inner strip is pre-profiled in such a way that when formed it is completely smooth to the touch. The surface of the stainless steel is completely fresh and has never been compromised, thus making it much more difficult for corrosion to set in. With some conventional flue liners, you will be able to see 'fine scratches' on the surface of the flaps, where the steel has been compromised in production. You will also very easily be able to pull apart the liner with your hands with no real effort. You cannot do this with Dura Flue. We welcome openly, all customers to come and see our unique manufacturing process at any of our depots so that we can show you the benefits of a Dura Flue chimney liner. 

We believe in high quality products, doing a job once and doing it right. - FLUE & DUCTING.

    "Although we use flue liners by 4 different manufacturers, mainly because it allows us to tailor-make stove packages to suit every customer, without a doubt, DURA-FLUE is by far, the best liner in terms of quality and manufacturing I have ever had the privilege of installing! "
