DuraChimney is a double-wall, air-cooled chimney system for use with masonry fireplaces which burn wood, oil, coal or gas. DuraChimney is an exceptional factory-built alternative to pre-fabricated masonry chimneys that provides a hot draft on the insude and proves a fire-safe design that protects both the chimney and the building.
