The DuraVent DuraPlus Round Chimney Cap is designed to stay cool on the outside, provide a hot draft on the inside, boost stove efficiency and has a fire-safe design that protects both the chimney and the building. This triple-wall chimney cap protects against dangerous sparks, helps prevent rain from entering the chimney and features two insulating layers consisting of a 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 is subjected to rigorous and stringent HT requirements of the UL standard, including 1-hour at 1400°F, plus three 10-minute chimney fire tests at 2100°F. Required where chimney pipe terminates above the roof line, this cap comes with a spark arrestor screen and has removable screws for easy cleaning.
