Perfect for stopping cold air leaks
January 10, 2018
Even after installing foam socket sealers cold air still pours through unused receptacles via the small openings for the electrical plugs on outside walls. These plastic outlet plugs fit snug are effective in against cold air infiltration. Unused phone jacks were doing the same thing and since I no longer have a wired landline I replaced the jack plates with blank plates and foam sealers. Every little bit helps when it’s ten degrees outside.
