We had a fire about 10years ago and they replaced our blown in insulation with that pink fiberglass and now our house is very cold and drafty. I am at a loss as to remedy this. We are going to work on foundation this summer, we live on limited income so can't spend a lot on doing this. This is a 10 room house all on one level, we only use about 5 rooms others are shut off. I would appreciate any suggestion as to how to make this house warm and cosy.
