I am digging out my crawl space. Want to insulate between the floor joists. The joists are 2x6's 24 inches on center. In many places I will be 'sistering' another 2x6 along side. What do you do in these oddball spaces. Do you trim the 22"± insulation to size or do you just cram it in.
Also, since I am doing it from beneath, what are my alternatives for holding the insulation in place. I would like to use paper-backed and will be installing it 'paper-up' preventing me from using a stapler.
All ideas and criticisms welcome!!
