In practice, the thermal resistance is never infinite. IOW, you can
add more and more insulation, but you can never reduce heat flow to
zero.

 The funny thing is, if you have insulation with sufficiently low
resistance around a cylindrical object, eventually adding insulation
reduces the thermal resistance, because the area available for
convection keeps increasing.  Sometimes this is even practically
meaningful.
 Just thought I would throw that in, as an excruciating detail.

Yep. I recall that excruciating detail from taking a Heat Transfer class many, many decades ago.
