DuraTech Additional Info:

Featuring thermal blanket insulation between dual walls, DuraTech delivers top-tier safety and performance. It maintains a cool outer chimney wall while ensuring high flue gas temperatures for optimal draft. The inner wall is 25% thicker than those in competing chimneys, providing an extra layer of safety. With no need for locking bands or mechanical fasteners, DuraTech’s sleek 1" wall design allows for easy installation through 16" on-center framing. For tight spaces, a Reduced Clearance Square Ceiling Support Box is available (6" diameter DuraTech only). Engineered for continuous operation at 1000°F flue gas temperatures, DuraTech meets rigorous UL standards, including testing at 1400°F for one hour and three ten-minute chimney fire tests at 2100°F
