The message
from "IMM" contains these words:

Not so. You do it in phases. You
don't dig a trench all around the
building. You dig out 1.5 meters,
install insulation and backfill, and
work your way around the house.

You have to take into account all
building types when you give this
sort of advice. Thre are very old
buildings with no foundations at all
which would possibly not survive
this treatment.

This is true. The building in question is a barn, which would have the
floor excavated, and a new floor poured with insulation under. A
massive
cold bridge would be to the side. This method solves that. In most
houses
with a concrete slab floor it would too.

Seems we can add a
