DuraTech Class-A Chimney System 6"x6" - Talk about innovation - DuraTech sets a whole new standard in quality, design, and performance for chimney systems. Using a compressed blanket insulation, DuraTech keeps the outer wall of the chimney cool while ensuring high flue gas temperatures for optimum draft performance. Encased between dual walls of stainless steel, Thermal Tech blanket insulation is locked into position. This eliminates hot spots common with loose fill type insulation's. No sifting, settling, or dangerous, voids. In the event of a creosote fire, compressible blanket insulation permits the chimney liner to expand outward in a radial direction. DureTech's free floating inner liner design also permits the liner to expand in a lengthwise direction. This eliminates buckling and loss of structural integrity associated with solid-pack type chimney. DuraTech's twist-lock connections require no locking bands or fasteners. Just twist the section to lock it in place. The DuraTech Support Boxes feature a built-in, twist-lock connection that ensures a safe, secure connection between the support and the chimney. The outer wall of DuraTech chimney is .016" 430-alloy stainless steel and the inner liner is .020" 430-alloy stainless steel. DuraTech chimney is tested and listed to the UL 103HT standard for use with wood, oil, coal, and gas appliances in 6", 7", 8" diameters; and the UL 103 standard in 10" and 12" diameters. DuraTech chimney carries a lifetime warranty, proof of the manufacturer's total confidence in this product. Once you get a piece of DuraTech Chimney in your hands, you'll know immediately this is a quality, user-friendly product. And all this at a competitive price. DuraTech wins hands down. All of these great features and benefits qualify DuraTech as the best class-A chimney on the market. Nothing compares to it.
