Hey, Excel. I'm glad to see your input on prep before installation of insulation. Our lowest temperature during winter is around the mid twenties, this low probably feeling like a sauna to some here who experience polar bear weather. My question is after installation of sheathing.
Do you spray seal the inside corners of the stud bays to prevent lateral and vertical air drift? I seal the holes for electrical wires with silicone after running wires.
