Framing a small shop within my unheated shop. Small area will be heated to= constant 50=B0 to obviate rust on my machinery. Have lots and lots of R-1=
9 left over from previous projects. Need to insulate 20 feet of 2x4 stud w= all. I know you aren't supposed to 'cram' insulation. However, if I do cr= am in the R-19 will I have less benefit than R-13 would have provided?Thanks for replies, Ivan Vegvary

But I think you end up with something around r13 so if you have it handy I'd use it.

fiberglass peels apart pretty easy, so it can fit well

There's no point, however. While there is some loss compared to full cavity thickness, the overall loss for 2x6 inserted into 2x4 cavity is less than the full-thickness starting for tubafore. IOW, as another poster noted, the net effect is less than what would get for insulation in a 2x6 wall but still higher than would have by using R11 as spec'ed for 2x4.

Use foam panels. There is some Polyurethane rigid panel that is almost
3x the r value of FG. ... and you don't get itchy.

What in the previous did not come thru?

I guess I assumed the right material was more appropriate than whatever you have left over. Rock on dude with whatever you like.
