DuraChimney® Description

DuraChimney® 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® 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® 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.

DuraPlus® Description

DuraPlus® is designed to stay cool on the outside, to provide a hot draft on the inside, to boost stove efficiency, and to provide for a fire-safe design that protects both the chimney and the building. This triple-wall chimney features two insulating layers (ceramic blanket, plus air space). The ceramic blanket insulation is held securely in position, eliminating hot spots common with loose-fill type insulations. In the event of a creosote fire, the compressible blanket insulation permits the chimney liner to expand outwardly in a radial direction.

Designed for normal, continuous operation at 1000°F flue gas temperatures, DuraPlus® subjected to rigorous and stringent HT requirements of the UL standard, including one hour at 1400°F, plus three ten minute chimney fire tests at 2100°F.

Applications
