I'm looking at increasing my storage by fixing up some space in the attic. The construction stuff I can handle, but have a question about the insulation. My attic has "blown in" insulation. I was wondering if I should (1) smash it down under the flooring or (2) push aside the excess so what remains at the floor line would have a "natural loft". Or, (3) would it be better to go with the pink stuff? Any help would be greatly appreciated. Thanks.
