With a Thermal Tech blanket insulation encased
between dual walls, DuraTech offers superior safety and performance. It
keeps the outer wall 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. Designed for
normal, continuous operation at 1000°F flue gas temperatures, DuraTech
is subjected to rigorous and stringent HT requirements of the UL
standard, including one hour at 1400°F, plus three ten minute chimney
fire tests at 2100°F.
