DuraTech sets the standard in performance. The ThermalTech blanket insulation in the lengths, elbow, and tees eliminates hot spots, with no shifting, settling, or voids. In the event of a creosote fire, this insulation lets the chimney liner expand outward and lengthwise, eliminating buckling and loss of structural integrity.
DuraTech uses twist-lock connections and features stainless or galvalume outer walls. Outer diameters are 2" larger than the inner. When double-wall stovepipe is needed, use DuraVent DVL.
DuraTech is tested to the UL 103HT Standard for use with wood, oil, coal, and gas appliances in 5"-8". Additional sizes and components are available by special order.
