Flexible Flue Liners
Flexible flue liners are designed for relining an existing chimney and creating a safe, efficient passage for flue gases from your stove. At Nationwide Chimney Components, we supply a wide range of stainless steel flue liners for wood-burning stoves, multi-fuel stoves, and many wood-burning installations, helping you choose the right chimney flue liner for your property and appliance.
Whether you are replacing old liners, fitting new liners, or planning a new chimney flue system, choosing the correct flexible flue product is important. Our range includes 316 and 904 grade flexible liner options, suitable for use in a masonry chimney where a durable flexible chimney flue is needed to cope with soot, moisture, and high temperatures inside the chimney flue.
The right chimney liner will depend on your appliance, fuel type, and installation requirements. When selecting a liner, it is important to consider flue diameter, flue size, and overall appliance requirements, as well as the type of stove pipe being connected. If you burn wood or certain smokeless fuels, the grade and specification of the chimney flue liner can make a real difference to performance, durability, and long-term value.
Our flue supplies are selected to help you complete a reliable installation from stove to terminal, including the components needed around the chimney stack and chimney pot. Every flue system should be properly specified and installed in line with the current UK Building Regulations and relevant guidance. For peace of mind, many customers choose to have their system fitted or signed off by a HETAS-approved installer.
If you are unsure which flue liners are right for your chimney, our team can help you choose the right flue liner, whether you are relining an older masonry chimney or upgrading a system for a new stove. You can also read our guide to chimney liner insulation for more advice before ordering.
