DuraChimney II is an exceptional factory-built alternative to pre-fabricated masonry chimneys. It 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.
