Is it worth it to insulate outlets? Sealing as many of them as you can is the trick to saving money because the more you seal, the lower the influence of the stack effect.

Can you put insulation around electrical outlets? Another simple step for better outlet insulation is to apply foam or caulk into the gap around the flush-mounted box, behind electrical cover plates. After foam hardens, you can slice off the excess with a serrated knife. To seal wall boxes, first seal the cable intrusions and then the gap around the box.

Can I use spray foam around electrical outlets? Never spray insulating foam inside an electrical box, as this can cause overheating of the wires.

How do I block cold air from outlets? You just unscrew the cover plate, place the foam over the receptacle, and screw the plate back on. Then plug in either an appliance cord or a child safety plug into each slot. If you don’t fill the slots, the cold air will probably come directly out of them. Repeat a similar process for switch covers.
