AC, this is very interesting.

I will be spreading loose fill in my garages attic. I need a total of 440 ft3 (12 inches thickness, 28 * 16 attic space)

I have 20 ft3 of styro peanuts, 240 ft3 of ground styro grains. I was thinking of spreading this on the attic floor, and then topping it off with 180 ft3 of cellulose. Or would it be better to mix it all together to minimize gaps within the styro layer?
