Used to do this with construction waste off insulation from the local Morton Building crew. I quickly found that it was far easier to pull the arrows out of the target, and that the targets lasted far longer if I shot the EDGE of the insulation rather than the face. I used 2x6 boards, all-thread and nuts to compress the insulation, then wrapped with duck tape.
After a few times doing that, I used ratchet straps instead to compress the layers together.
Works just as well with cardboard also.
BUT, here's the bad part.
If you shoot a lot, the insulation isn't very durable. I got to where I could wear out an insulation target in a week while I was in college. Even just shooting my old 80lb recurve, I'd eat up an insulation target in a couple dozen shots with broadheads.
