    I have a question about how to best insulate my crawl space. My house was built in 1972, and basically what I have is 4 x 8 beams running the length of the house, with 2 x 6 for the subfloor with plywood on top. Now the beams are 45" apart. What would be the most economical way to add insulation to this?
