DuraVent's DuraPlus is a UL 103 HT-listed, all-fuel triple-wall chimney system built for wood, pellet, and oil-fired appliance installations. Two insulating layers — a securely-held ceramic blanket plus a dead-air space — keep the outer wall cool to the touch while maintaining a hot, efficient draft on the inside. This listing is for the 6" diameter DuraPlus system.
