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, allowing for faster installation.
Designed to stay cool on the outside, and to provide a hot draft on the inside to protect both the chimney and the building.
The double-wall, air-cooled design allows the chimney to expand both radially and lengthwise under high temperatures.
Outer diameters are 3" larger than the inner.
