Thermal Tech blanket insulation encased between dual walls, DuraTech offers the optimum in safety and performance. It keeps the outer wall of the chimney cool while ensuring high flue gas temperatures for optimum draft performance. The inner wall is 25% thicker than competitive chimneys for an extra margin of safety. No locking bands or mechanical fasteners required. Designed for normal, continuous operation at 1000 deg F flue gas temperatures, DuraTech is subjected to rigorous and stringent high temperature requirements of 1 hr at 1400 deg F, plus three 10 min chimney fire test at 2100 deg F.
