Twin Wall Flue Systems

Twin wall flues are insulated chimney systems for open or closed solid fuel stoves, condensing and oil fired appliances. They can withstand continuous operating temperatures of up to 450°C and are perfect for wood burning stoves, gas coal effect fires and oil boilers. Great for new build and renovation projects as they are a simple and cost effective solution for those without a brick chimney stack or an existing chimney stack, so you can install a stove in any room.

Twin Wall Chimney Flue Essential Info

Nationwide Chimney Components supplies premium high quality twin wall flue systems and twin wall flue pipes, including stove pipes, to meet your heating requirements. Our twin-walled flue products have adjustable-length pipes for indoor and outdoor flues and biomass boiler installations.

They have a simple twist-lock bayonet jointing system and are available in high-grade stainless steel or black twin-wall flue pipe in all sizes. HETAS approved so they meet building regulations. We also supply all the flue installation materials compatible with multi-fuel stoves to make installation easy and compliant.

The external diameter of double-walled flues is 60 mm more than the inside diameter. So, a 150 mm pipe has an outer diameter of 210 mm. Our twin wall flues can pass through floors, roofs, or walls, depending on your required flue route.

We stock the Schiedel flue system and are one of the UK’s leading providers of flue supplies including chimney cowls and flexible flue liner.

We also offer a comprehensive range of flue installation materials, such as wall support, wall storm collar, locking bands, roof support, or a simple starter length, which ensure compatibility with multi-fuel stoves and ease of installation for both existing chimneys and new constructions without an existing chimney stack.
