Posted a few questions on the Heating board and got side tracked to insulation....So, I just had my basement band sills and the walls (going down three feet)spray foamed. I am under the impression that these are areas that can allow a lot of air infiltration. Appreciate any thoughts on this. Also, all my boiler hydronic pipes from the boiler to where they go up into the floor are all wrapped in foam insulation. I have heard both pros and cons on this. Again, any thoughts on this appreciated! Bill
