I took a picture of this blue box to highlight how hard they are to seal. If you look at the bottom back of the box, you will see small black slots which form an opening for a wire penetration. Each one of these slots,is an opening into the stud cavity for interior air to migrate into, on the negative pressure side, and cold air to enter the house on the positive pressure side of the house. There are about 32, 1/16th x 1 inch slots in this box, which is 2 sq inches of leakage, not counting the leakage around the drywall to box interface.
