Those three walls consist of a stainless steel outer wall, an aluminized steed middle layer, and a stainless steel inner liner. That combination makes the pipes incredibly durable during repeated use and corrosion-resistant to boot. The exterior of the pipe features an airspace and a ceramic refractory blanket, providing insulation to the extent that only two inches of clearance are required to combustibles. When you want a great vent pipe, a limited lifetime warranty, and unbeatable function your only option is DuraPlus All-Fuel Stainless Steel Chimney Pipe.
I would recommend this item to a friend.

Well made. Pipe fits together easily and securely. Would have got 5 stars except the inner pipe and outer walls were bent and I had to straighten them out. I do not think this was done in the shipping process because the boxes were not damaged.
