We recently purchased a new home (new construction). As the weather has gotten colder, I've started to notice cold air coming in through my electrical outlets and light switches. (The light switches are actually cold to the touch.) This is only occurring on the first floor of my home and only along the northern exterior wall. Outlets on all other exterior walls, and even the northern exterior wall on the second floor, are fine.
The one thing that has me concerned is that the home is an "Energy Star" home, so the cold air in the outlets and light switches was very unexpected. I know that they used Tyvek wrap along with several other insulating features when building the home. (If you're interested in reading more about their insulating technique, it can be found on their web site here...
Thanks in advance for any and all responses!
