Foam Electrical Box Protection
Here's a insulation homeowner tip, if you ever
remove any drywall or sections of the exterior wall that will expose any
electrical boxes you can insulate them.
In the picture above, we sprayed a foam insulation around the electrical box to prevent air or moisture from entering the living area through the gaps around the wires.
This is something simple and inexpensive and can be quite effective when insulating a home. You can use caulking as an alternative to spray foam insulation.
