DuraTech 5"-8"
With a Thermal Tech blanket insulation encased between dual
walls, DuraTech oers the optimum in safety and performance. It
keeps the outer wall of the chimney cool while ensuring high ue
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.
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 ue 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 re test at 2100°F.
