I have some exterior walls exposed due to another project. I want to replace the crappy fiberglass batt insulation with foam board insulation.
For a retrofit/remodel like that I would go with spray foam. Google on 'Froth Pak'.
What should I do about a vapor barrier? Inside or outside surface or none?
That would depend on your location. Generally in Cold areas the barrier is on the inside. And, with spray foam, you may not need a barrier at all!
Good Luck!
