My house is too darn cold! Even at 68 degrees I am still cold! got blankets and layers of clothes. Must be me LOL! However we live in the brick house with plaster and lathe walls and I can not figure out how we can install insulation. I remember redoing the bathroom, installing a window with my father, there was a gap between the studs and brick which it probably a good foot empty space. No insulation at all except upstairs floor. Nothing on the roofing either. Wooden floors throughout the house. No insulation on the bottom of first floor and no insulation in basement walls or basement ceilings. The north and west sides are awful, you can feel the cold draft feel to it even we had new replacement windows installed. Spray foam or rolled insulation? I am not sure how insulation can between the brick wall and studs without getting any kind of moisture, since we do need to get the bricks repointed. This house is built in 1938 I believe. Would the installers need to put holes in my walls to put in insulation or take the brick out?????? We do not have alot of money an dtime to tear out walls but if we do, it might be the way to go but it wont happen in a few years. Or do we need to rearrange the furniture? I can put the TV and sofa on the cold walls and move the recliners inside walls. The old heat ducts, one in a room, is in the inside wall instead of under the windows. We have two huge cold air ducts, one in hallway and one in living room. (is it a real need for TWO cold air ducts???) The warmest room is my daughters room. Nice and toasty. Bathroom is the next warmest. I know we installed insulation on the outside wall and one side of inside wall (behind it is the stairs going downstairs). Rest of the rooms are cooler and uninsulated. Maybe I should turn up the heat a bit more this year!
