i replaced a socket yesterday and noticed a lot of cold air coming thru the slots. Where is this coming from? how do it fix it? i put childproof plugs in the unused ones :).

I understand that this is pretty common. I would think the child proof plugs would help. My parents 20 year old suburban house does this as well. Not sure what causes it though! Maybe some physics behind it such as a natural vaccum forming between pressure outside that comes due to a different pressure inside the home. Could be caused by air temperature differences between your house and outside?
It comes from air moving inside the wall due to lack of or insufficient insulation. You can get foam covers at most home centers to install under the plate, it will hep some.
