so maryland/local utilities have teamed up to let me write off 50% of insulation costs, and it sounds like this applegate rfoam is the best thing since sliced bread. Has anyone used it? it's some expansive low expansion foam that apparently can turn a studded 2x4 space into R16, which sounds nice.
my concern is that I have original wire in the wall for electrical, it's BX with 2 pair romex inside. so I've been used the metal shielding as the ground, and it works. I just know that the applegate foam will make it hard to run wire (impossible), but it's in great condition so should I not worry?
thoughts/experience with the applegate rfoam or other options?
