DuraTech sets the standard in quality, design, and performance for chimney systems. Using ThermalTech blanket insulation, DuraTech keeps the outer wall of the chimney cool while ensuring high flue gas temperatures for optimum draft performance. This also eliminates hot spots common with loose-fill type insulations.

In the even of a creosote fire, this compressible blanket insulation permits the chimney liner to expand outward. This free-floating inner liner design also permits the liner to expand lengthwise eliminating buckling and loss of structural integrity associated with some solid-pack type chimneys.

DuraTechs twist-lock connections require no locking bands or other mechanical fasteners.

The outer wall of DuraTech chimney, in 5"-8", is .016" 430-alloy stainless steel and the inner liner is .020" 430-alloy stainless steel.
