It sound's like a dumb question but I it was asked of me the other day. We were doing a new construction addition and the customer wanted some outdoor outlets installed. We did the usual 1900 box with a large extension ring. Afterwards the customer asked "How does that seal from the elements and insects. The box has holes in it and a insect could get through the bubble cover and into the walls. Cold air the same way." I explained to her about the gasket and how it's also sealed from the outside with the siding.
She does bring up a decent point that I have never thought of. Metal boxes are code here so that's what I have to work with. I thought a remodel would work but sucks if you ever want to pull though again. This is just how I always did it and always figured "The caulk on the outside and insulation on the inside will be enough".
How has everyone else handled this? WP boxes aren't an option because of looks. I was thinking some sprayfoam encasing the junction box from the inside. (Inside the house not the box. I did a service call where a homeowner did that....what a nightmare!)
