My house is pier and beam. Does anyone have any suggestions on the best way to insulate under there? The house sits up off the ground about two feet and there is no skirting so it is open.
Someone told me to get large styrofoam blocks and strap them up underneath. Sounded good but would give rodents and bugs plenty of room to make new homes. Same goes for fiberglass insulation.
I thought about having that spray foam sprayed under there, but am worried it might hold moisture between it and the wood sub floor?
