What to Compare
For Florida attics, spray foam on the roof deck (conditioned attic) is the premium upgrade that genuinely pays back over time — it keeps ducts in conditioned space and cuts AC bills. Fiberglass blown-in meets code and is the cost-effective standard. For walls, fiberglass is typically fine in Florida.
