Foam board over existing siding
Thoughts on adding continuous foam board over existing cedar plank siding? I’m renovating a vacant home to be all-electric and extremely airtight/energy efficient. The home was built in 1929 and has 2×4 stud walls with no insulation. The current plan is to do dense-packed insulation from the exterior before wrapping with continuous foam board. I get mixed reactions on this.
