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

Thanks for replies,
Ivan Vegvary

The theory is that when you compress fiberglass insulation you reduce
it's r factor because of increased condutivity. 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

You will get better noise reduction, and better fire proofing through the
wall.
