I'm buying this 1947 house from a guy who did a bunch of strange things. I'm not entirely sure put he may have used polystyrene foam. The other thing is there is no vent in the roof, someone told me it didn't need it for this building. I guess i won't know what's in there unless i open it up. I guess it should have a vapour barrier. There is no heat this attic bedroom either. Since we are the topic i'm wondering what to do about the heat in this house. The force air furnace definitely need to be replaced in the basement. The forced air heat the main floor only. I was thinking of instead putting a gas fireplace on the left side of the house under this attic bedroom. I wonder if a gas fireplace could adequately heat this size house? Perhaps a heat pump or electric baseboard heaters on the second floor? I was reading that heat pumps are cheap and efficient then other people told me they are expensive to run. I guess the insurance want the forced air because of the issue of freezing pipes in the basement. Also the gas bill was 1800 cnd last year to run this 1983 furance, i guess that indicated no insulation? I was thinking to take the board off where the evesdraught is seem if can blow insulation up there. This polysterne probably isn't so good from what i understand, looks like he completely finished this room.
