Twin Wall Flue

Twin Wall Flue

Twin wall flues are an insulated chimney system designed specifically for use on open or closed stoves. With continuous operating temperatures of up to 450°C. The insulated twin wall flue system is designed so that the outer case is load bearing and the inner flexible flue liner is free to expand independently. Therefore thermal expansion is accommodated within each and every joint. Twin wall flue pipes and accessories for wood burning stoves are a simple, cost-effective solution if you dont have a brick chimney stack, making them ideal for new-build projects and renovations. Our Twin wall systems are a simple twist-lock bayonet jointing system. They are available in both a high-grade stainless steel finish or as black chimney flue pipe in all sizes and are HETAS approved. This system can be used when you have no existing chimney stack. They can pass through floors, roof or walls depending on your required flue route. The quality, manufacture and finish of twin wall insulated flue pipes can vary a great deal. NCC only supply premium high-quality double wall components. We stock the Schiedel twin wall chimney flue system and are one of the UK's leading supplier of twin wall insulated flue systems.

Twin Wall Flue Features

  • Twist-lock push fit bayonet jointing system. Secured by locking band.
  • Advanced corrosion resistant design and construction uses laser.
  • Welded 316L stainless steel inner liner and stainless steel case.
  • The 25mm of high-density Rockwool insulation maintains flue gas temperature, maximising efficiency, improving flue draught on startup and minimising condensation.
  • Low external case temperature.
  • The inner liner is free to expand through the female collar. Allowing for maximum thermal expansion even during a soot fire.
  • The inner liner has an inward bead at the female end which acts as a capillary break preventing moisture being drawn through the joint.
