"super" flue tile ?

[Nicholas]

Still planning here
When I built my 1st house (1990) with a dedicated wood stove chimney, I recall reading about a "super" flue tile.
It was dimensionly the same as a clay liner, but made from a material that "could" withstand something like 2000 deg ??
If I recall it was "gray" in clor?
Anyone have any info on "upgraded" flue tiles?

Thanks,

Nick

Why use flue tiles? Run a Class A HT chimney and that's rated for 2100F. You can make the chase out of stud walls and put real brick on it if you want, or cultured stone or even vinyl siding.

A masonry heater uses flue tile for the 1st 6-8 feet of chimney - at least.
Then some convert to class A, some are masonry all the way up.

Problem comes in if you install a bypass (to dump the exhaust directly into the chimney) some heater masons have said the 1st flue tile can get heat damage.
The bypass is used to burn a fire without heating up the masonry mass. (romance fire).

But for the 2nd flue (basement wood stove) I am trying to get all my options (class A wrapped in masonry, flue tile, super flue tile)
