DuraVent DuraTech 8" Diameter Galvalume Steel 24" Pipe Length

With a Thermal Tech blanket insulation encased between dual walls, DuraTech offers optimum 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 are required.

DuraTech’s sleek 1″ wall design provides for easy installations through 16″ on-center framing. For tight installations, a Reduced Clearance Square Ceiling Support Box is available (6" diameter DuraTech only).

Designed for normal, continuous operation at 1000°F flue gas temperatures, DuraTech is subjected to rigorous and stringent high-temperature requirements of the UL standard, including one hour at 1400°F, plus three ten-minute chimney fire test at 2100°F.
