Spray Foam in Hot-Humid Climate
I am looking into installing spray foam in my roof deck in a hot and humid climate. I was planning on spray foaming the attic for both my house and the attached garage and shared wall within the attic.
Based on some recent reading, I am hesitant in using open cell due to humidity rising and sustaining the roof deck. I’ve read that air conditioning within the attic can reduce these problems
