Weatherproof Outlets and Light Switches
Don't forget to seal those hidden areas
What's going on behind those wall plates? Loss of heat, that's what. So use foam gaskets to seal switches and outlets. Air can
leak through interior walls, flowing up into the attic, as well
as through exterior walls. So install the gaskets on all outlets
and light switches on all your walls. Plastic safety plugs can
be used to stop air leaks through unused electrical outlets.
