It all adds up. The floor is a large area and added to the dwarf

reasonable percentage of the overall area, so worth insulation well.
If
the
conservatory is against the outside wall of the house the conservatory
acts
as an extra layer of insulation on that wall. As no rain will
penetrate
this section outside wall, full filling the house wall against the
conservatory is a good thing.

The problem is getting inside the cavity, so
a spray in foam would need to be used.

built.

The existing house wall. Duh!

The question was about the new wall not the existing. Try to keep
up.

You must learn to focus.
