Insulation for wood insert

I think this should be OK at 2000° just wanted to reach out and make sure that this insulation is sufficient for insulating around my liner and damper as well as around the top of the chimney between the clay liner, and the stainless liner

Yes, it's mineral wool. Not fun stuff to work with. Wear a mask.

You need clearance from the outside of the brick structure to any combustible materials. For an internal chimney it's 2" external is 1". Unless you have that the liner needs insulation
