Any suggestions of what is the most painless way to do this. We are considering everything from liquid insulation to carefully tearing down the ceiling/walls , putting rigid foam on the walls and trying to re-attach the same panels.
In any case, it would be much easier to rip down the ceiling (which wasn't well done). This would allow us to add insulation in the ceiling and lay it around where the foundation attaches to the house, which leaks alot). Is the extra effort of ripping down the walls going to help our situation enough to justify itself.
