Thank you for your time to answer my question!
I have 700 square feet to insulate -- is an attachment room to a frame house, built very poorly, and is very cold and hot. I'm doing now fixing up.
Question: I have walls 3 inches deep, and celling is 12 inches deep. I was going to spray foam with closed cell.
Can I maybe (to reduce cost) install fiber insulation? Or styrofoam, 1-2 inches, then spray with closed-cell over that?
Or is it a good idea to spray one inch of closed-cell and do the rest with open-cell over closed-cell?
