8'' DuraTech Insulated Wall Thimble - 8DT-IWT

The Insulated Wall Thimble adjusts from a minimum of 5½" to a maximum of 9½" wall thickness, fits between standard wall studs and the interior trim is painted black. To accommodate thicker walls, the telescoping pieces can be extended up to 16" when a field-fabricated extension is installed. The Wall Thimble must be installed with DuraTech chimney pipe horizontally through the walls and extend 6" into the room beyond the interior walls.

DuraTech is a double-wall, all-fuel chimney system for use with wood stoves, fireplaces, furnaces, boilers, ranges, water heaters, or other appliances fueled by wood, oil, coal, or gas, and zero-clearance fireplaces that are factory-built.

Additional Information:

With a Thermal Tech blanket insulation encased between duel 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.
