Twin Wall Flue

Twin Wall Flue

Twin wall flues are specialised insulated chimney systems designed for use with open or closed solid fuel stoves. They can withstand continuous operating temperatures of up to 450°C and are perfect for heating appliances such as wood-burning stoves, gas coal effect fires, and oil boilers. These flues are ideal for new build projects and renovations as they are a simple, cost-effective solution for those without a brick chimney stack. Take a look at our article on fitting a twin wall system.

Nationwide Chimney Components only supplies premium, high-quality twin wall flue systems and twin wall flue pipes. Our twin-walled flue products include pipes with adjustable lengths, making them suitable for indoor and outdoor flues and biomass boiler installations. These products have a simple twist-lock bayonet jointing system and are available in high-grade stainless steel finish or black twin wall flue pipe in all sizes. They are also HETAS-approved, ensuring that they meet building regulations.

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 and flue liners.
