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!!
