Cold air is leaking through the outlets and light switches on exterior walls, making rooms cold and drafty.
Frost King has a selection of easy-to-install Outlet Sealers that provide insulation and block drafts that are coming through poorly insulated electrical boxes. To install, just turn off power to the outlet or switch and remove the cover. Place the socket sealer over the opening, and then screw the cover back into place to block drafts for good.
