Can I go through the brick wall exterior to blow in insulation? I dont really want to but want to know if possible. I had family do this in Scotland recently.
We are working on various rooms in terms of painting - should we do a room at a time making holes in the sheet rock and blowing insulation from the inside? What are the ramifications of having some parts of the house that are wall-insulated and some that are not?

Doing it that way will end up with a moldy mess inside the wall.
Consult with a spray foam company. Not cheap but it works.
It's not a DIY job.
Lot's of times in a home that old It's air leaks causing the real problem.
Old single pane windows, pockets for the old window weights that are any empty space that if you removed the casing you would be able to see daylight inside the space.
No insulation under or around the jambs.
No fire blocking at the bottom and tops of the walls so air can flow from the crawl space or basement all the way to the attic.
