Whether your electrical outlets are vapour sealed is unknown. I can’t remember at the moment what year that came into code.
In any event, you shouldn’t find water pouring down the outside walls no matter what. Hope you get some answers from the envelope perspective. Please report back what you find or don’t find! |
It would be a real easy check for outlet vapor barriers, pick any plug or switch on an exterior wall, pull the faceplate off and shine a flashlight between the cut out drywall and the box itself.
The vapor barrier should be very noticeable. Also I'm not sure when they were added to code, but they've been code for at least 20 years now
