Do you think this energy loss all over the house doesn't add up?
Perhaps 10% of the energy loss in your house happens through exterior wall penetrations like receptacles, switches and canister light fixtures.
Spots this poorly insulated can be a significant loss of energy over time!
Some builders will put foam around each one, but many will not. That foam is a good insulator.
And how many wall switches, receptacles and light fixtures are in a house?
And while it isn't a swoosh of energy, often in cold weather you can actually feel air coming in through receptacle holes.
Remember, heat seeks cold.
Small holes, and gaps, and missing spots of insulation add up to significant energy losses. And you are paying for that over time, and the problem doesn't get better.
What can you do about spots like this?
There are small foam receptacle inserts that can easily be put into each receptacle and switch plate.
While they aren't 100% effective, they are better than nothing!
They are made to fit into all sorts of different shapes of receptacles and switches.
You simply punch out the pattern desired and slip it in!
My recommendation: if you feel air moving you are essentially feeling energy moving in or out of the house. That has to be stopped somehow or it will be a continual thing. Physics works every time. Next cold day, or maybe a very hot one, put the back of your hand against a wall plate and see if you feel air. If so you may need to insulate it better. The foam inserts are very cheap! And will pay for themselves in short order.
