North Central US | For a house built in the late 50s, all wood construction, with additions in the late 60s, and from the pictures of construction no type of wrap was used, how much would it help with heating and air conditioning?
Is it a bad job to do? The house has steel siding on it, all with holes pre cut in them for your nails to go through.
Would the money be better spent on more attic insulation? | |
