My second electical question of the morning…
What’s the best way to air seal an electrical box (outlet, switch, etc) in existing construction? I’ve got rocklath (plaster) walls, if it matters. I have some of those foam gaskets but, those aren’t really made for gang boxes, switches, etc.
Should I caulk on the inside or foam it on the inside of the box? Will that make later renovations harder? Do I need high-temp caulk or foam if I do that?
