I am going to be building a relatively small (1600 sq/ft) new home here in northern Illinois. I have been advised by several of my friends to insulate the home with spray-in closed cell urethane foam insulation. I have also been searching and reading as much information about this technique as I can. I wanted to ask if you have experience with this and what you believe to be any advantages or disadvantages. My concern has been about moisture condensation. But what I understand is that the current thinking, by those companies who have been installing this for years, is that by sealing so completely, thus eliminating air currents condensation does not occur.
I will be anxious to hear your thoughts.
