Cookeville 4.14.25 - Monday (1 PM) Closed (#224767578)

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 2-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 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. Material Galvanized Steel.
