Our 6" high quality Dinak Twin Wall range of insulated flue pipes have an accurate 150mm internal diameter, 30mm of compressed insulation and an external diameter of 200mm.

The 6 inch Twin wall chimney flue is externally 8 inches; the external diameter to connect this to the single wall pipe requires an adapter that goes from single wall to a 6 inch twin wall pipe. Every 6 inch twin wall flue part comes with a free up to 45 degree joint seal, also for the use with pellet stoves. Dinak DW flues are a push fit system that requires a locking band for each component of which these are sold separately.
The Dinak DW twin wall has recently been given the EI 120 and EI 90 certifications for smoke control conduits, making Dinak DW flues the only flue manufacturer to obtain both these 2 certifications. Being awarded the EI 120 certification means you can have both for vertical and horizontal set-ups meaning the Dinak DW twin wall has become the first European metal chimney and conduit to hold this certification.
