Guys I am not a builder and learning as I go on my cabin build. I have started a cabin with a small foundation crawl space. I took some of the left over morter and filled in some of the blocks down to the footer and some were already filled with the bolts. I am putting green board styrofoam on the outside down to the footer as well as the inside before I vapor barrier it and scratch coat. A buddy stopped by and said if I wanted to further insulate the foundation theres a product out made of plastic resin that I could pour down the cavity. So this got me thinking could I fill each remaining block with Styrofoam packing peanuts? Would this help any at all or hurt any at all or a total waste of time?

Korfil makes polystyrene inserts for standard size CMU's that offer about R5 per inch . You buy the insulated CMU's with the inserts already installed. I have laid them occasionally. That doesn't help you since your block are already laid.
I have more often have filled cores with perlite which is commonly used as insulation in CMU's. With an 8" standard block you can bump your R value from 1.96 to 3.26, R2.08 to R3.82 with 10" block and R2.14 to R4.32 with 12".
It costs about $5.00 per 4 cu. ft. bag.
I agree with White, I don't think packing peanuts would make very good insulation. Some of the newer ones are even biodegradable. The polystyrene boards are a good choice for your application.
Eh...wot?
