Foam Outlet Insulation Stops Cold Air Coming Through Electrical Outlets
The small air gaps around electrical boxes on exterior walls and ceilings leak more air than you might imagine. In fact, a mere 1/8-in. gap around just six ceiling boxes is the equivalent of cutting a 4-in. hole in your ceiling. Think of the amount of heat you’d lose! When you combine that with the leaks around all the electrical boxes in outside walls in your house, it’s no wonder your house feels drafty.
