Currently i am in the process of refinishing the hardwood floor and trim in our stove room. After the removal of the trim it revealed just one of the many drafts in our old house. Below are a few pictures. The previous person just had some fiberglass insulation stuffed in the large cracks. What would be the best way about to go about sealing this up? Below this room i have access though the basement to the edge of the walls so my thinking was to tack 1" celotex (have a few 4x8 sheets) from the bottom to the edge of the wall and then from the top spray expanding foam insulation to fill the voids. If this in not a good idea by all means tell me and if there is a more effective way of going about it please let me know. Also, if the expanding foam is the way to go are there better types of it other than "Great Stuff" they sell at Home Depot?
Also, how effective would it be if i put fiberglass insulation in the rafters in the basement ceiling? The basement is unfinished with all exposed stone walls. It seem like last winter (first winter in the house) there was always cold drafts coming from the floor boards and the floor it self was always ice cold. I am trying to get the most bang for my buck and this is one of the areas that has absolutely no insulation. The other spot in the house that has no insulation is in the second story room directly above the stove room. This was the only room in the house that was not redone when the house was remodeled. At the least before the real cold gets here i plan on tearing the ceiling out and putting insulation in and add insulation to the walls.
