Cellulose or fiberglass to insulate floors above encapsulated crawlspace?
Year ago I put in some major sweat, blood, and tears to turn most disgusting crawlspace on the East Coast to something I remove shoes to walk on now. Radon levels are down too. I got all 1st and 2nd floor walls densepacked. MIni-splits are doing great. But I have one room above the crawlspace with hardwood and floors are really cold. This also happens to be room my in-laws come to stay (aka “free daycare”) couple times each month and my mom-in-law really hates how cold the floors are. Temprature in the crawspace hovers between 47 and 57. Moisture runs about there too, since I have ventilation between it and the large basement next to it.
So the big question:
Insulweb the 8″ deep floor joists and try to blow in cellulose or go the route of adding R19 of the pink stuff?
Whole basement is something like 1200sq ft (walls insulated) and crawlspace area is only 300sq ft.
Just want to give warm(er) floors for my in-laws, since they are so kind to help us out with our kid.
