I'm replacing my useless FP insert with a freestanding wood stove sitting a few feet from the wall where the FP used to be. I'm to the point finally that I need to run some pipe and all my research has clearly indicated that triple-wall class A pipe is the pipe for the attic all the way out. So I call the only dealer around and he says no one uses that anymore, they used 'double-wall insulated'. I'm told it meets the 2100 degree test. It's also $212 for a 4' piece. So is this true or should I deal with another vendor?

I see, so triple wall is 2" larger. My stove will use 8" pipe, wouldn't it still be 8" on the other side of the ceiling in the attic where the Class A pipe connects? Or do I understand correctly that what was an 8" triple wall is now a 6" double wall that is designed to fit to a specific adapter in the attic?
You'll still see triple-wall DuraPlus class A pipe sold at some big box stores. It's a value line of pipe and is still class A. It is bulkier to install and requires a bigger hole in the roof, but it will do the job. My personal preference is for the double-wall insulated DuraTech pipe in that brand.
I think you are not understanding. Triple wall is larger OUTSIDE. They will all be the same inside in accordance with the specifications of the mfg of your stove. I have 8" inside pipe because I have a huge stove. Most stove pipe is 6". Only the inside measurements are quoted, just as water pipe, etc.
