Open cell spray foam in attic
I am renovating a house in South Florida built in 1976. There is a new shingle roof that was just installed, I’m looking to insulate the roof rafters with 5″ of open-cell spray foam and condition the attic.
Is this the way to go? I am getting conflicting information regarding open cell and closed cell.
Do I need a dehumidifier?
I will be using a VRF HVAC system
