Closed cell spray foam in the floors/ceiling
I can't find much information about using closed cell in the ceiling/floor of living spaces. My house was specified to have closed cell for the envelope and also the living space. We did want insulation between floors to deaden sound but I am curious what the thoughts are on this method. My primary concerns are being able to snake electrical wires in the future. I don't believe it would be sprayed full depth so there would still be an air gap.
Assuming this is already built in to the price, is this definitely something we should do or should we switch it to something like batt for the floors?
