One home weatherproofing step I am taking is to add foam insulation inserts behind the plastic covers on power outlets in my home.
Mine is a 120 year old brick Victorian, the end unit in a row of four.
Question: I can feel the cold (this is Canada) on many of the outlets, especially those on the outer walls. Is it worthwhile or necessary however to insulate the other ones, the ones on internal walls, the walls between the houses and between rooms? Is there heat loss there too?
Thanks,
Peter
