DuraTech Roof Support is designed to support
the chimney and allow the chimney to pass through the roof and extend
down from the ceiling. It is ideal for cathedral ceilings and
free-standing fireplace installations supporting up to a maximum total
chimney length of 45’ and 20’ below the roof support. DuraTech Roof
Support is adjustable to accommodate different roof pitches. The trim
collar required for this installation is not included and must be
purchased separately.
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.

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.
