DuraChimney II is an exceptional factory-built alternative to pre-fabricated masonry chimneys. DuraChimney II is a unitized, lightweight design that eliminates the need for field assembly of pipe sections, allowing for faster installation.

DuraChimney II is designed to stay cool on the outside, to provide a hot draft on the inside, and to provide a fire-safe design that protects both the chimney and the building. The double-wall, air-cooled design allows the chimney to expand both radially and lengthwise under high temperatures.

DuraChimney II is tested and listed for continuous operation at 1000°F flue gas temperatures, one hour at 1400°F, and ten minutes at 1700°F, in accordance with the UL 103 test standard.



  • Use elbows to offset obstructions such as rafters, ridgepoles, or joists
  • 10”-16” DuraChimney II may have two pairs of elbows if needed.

Offsets greater than 30° are not allowed.
Elbows are not adjustable.
