More is always better.

Except around a pipe!!

???
Sorry, I was just making the point that whereas increasing the insulation
on
a plane surface is always additive hence your supposition "more is
better",
on a pipe it is not so.

It depends on what you want to do with the insulation around the pipe. If
you want to prevent heat from a pipe heating up say a cupboard, then more is
better.
