My goal is to insulate the crawl spaces and my basement for sound and temperature. That is why i was thinking about putting the blue foam board over the insulation after its up, but i don't want to make something else bad by making the floor sound proof.
So I should not use the blue foam board and just put the insulation in the rafters?
I am just worried that little pieces of insulation would fall over time so I wanted to cover it with something if possible.
The previous owner put blue foam board on the rafters and i removed it, Here is a pic of one of the offending areas i want to insulate. I already put 6mil poly covering the walls and floor.
