Are you installing a twin wall insulated flue system?

Twin wall insulated flues are the perfect choice for both new-build projects and renovations as they provide a simple, low-cost and effective solution for removing smoke and gases from building interiors. At Flue Supplies, we offer a variety of products, ensuring that you can find just the right system for your project's requirements. We are a family-run business with over 20 years' experience in the provision of flues, as well as other chimney products and accessories. Our dedication to excellent customer service and high-quality products makes us a trusted supplier that both trade and DIY clients return to time and time again for all their flue needs.

The benefits of twin wall insulated flues

If you are installing a new heating appliance, such as a woodstove, gas coal-effect fire or an oil boiler, you will probably need a twin wall flue system, especially if you do not already have a brick chimney stack. Twin wall can be constructed to produce a safe chimney system for your appliance.

These double walled flues are suitable for the creation of both indoor and outdoor flues and they can be used to pass through roofs and floors. They are waterproof and resistant to corrosion, meaning they will keep your home warm and dry for many years. Additionally, since these products are prefabricated in a variety of shapes and sizes, you simply need to mix and match components to get a system that fits the requirements of your project.


When installing any chimney system, it is important to remember that the completed structure should be as straight as possible. Always avoid unnecessary bends as these can reduce the amount of upwards draft or create a potential fire hazard. The double skin flue systems offered by Flue Supplies feature a simple push-fit joint system, ensuring that installation is quick and easy. They are fully welded and made from a high-grade stainless steel, fully approved by HETAS. Our collection of flue products and accessories are offered in a number of sizes, so you can find the system that best suits your requirements. Internal diameters available include 567, 8, 10 and 12 inches and various adaptors, bends and tee joints are also available enabling you to create a twin wall insulated flue system that fits your exact requirements.
