DuraChimney® II
DuraChimney II is an exceptional factory-built alternative to
pre-fabricated masonry chimneys. DuraChimney II is a unitized,
lightweight design which 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.
