    • DuraTech Class A Chimney Components

    DuraTech Factory-Built Chimney System

    • 430 alloy stainless steel inner wall
    • 2" clearance to combustibles
    • Listed to UL 103 HT
    • Limited Lifetime Warranty if installed by a trained professional installer

    DuraTech sets the standard in performance.  The Thermal Tech blanket insulation in the lengths, elbows, 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 and listed to the UL 03HT Standard for use with wood, oil, coal, and gas appliances in 5"-8" diameters.  Additional sizes and components are available by special order.
