That is my understanding - and there's not much point anyway if a
chimney is being built as it's easier to use sectional clay liners
or whatever it is they use these days.

Exactly so.
There are flexible liners specially for woodburners, some are twin
wall.

I believe *all* solid fuel flexible flue liners are twin wall
stainless steel.

mmm no "specially for woodburners" flexi liners there, just usual
"solid fuels" twinwall ones....??

It is possible I was mistaken looking at that. The bit of offcut I saw on
mine looked like one thickness, but if the inner lining is just to smooth it
out, I may not have noticed that as it was cut with tin snips so the two
walls were probably pressed together. I was thinking "twin wall" would be
thicker somehow. I apologie for being misleading.
