Twin Wall Flue
Twin Wall Flues
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 system is designed so that the outer case is load bearing and the inner 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, making them ideal for new-build projects and renovations.
Twin Wall Flue Features
- Twist-lock 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 start up 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.
