Will fiberglass insulation grow mold? (Florida)
This question could get flagged as opinion based but here goes anyway. I live in South Florida and have been in hundreds of attics with fiberglass insulation and have never seen any problems. Yes, there is a lot of humidity but if the attics are vented with soffits, etc., then the humidity doesn't cause a moisture problem. I had a roof leak and some of my fiberglass insulation got wet. I fixed the leak and monitored the insulation and it dried out in a day or two and did not compress. fiberglass insulation has been proven to be an excellent insulator. I have read some articles that warn about fiberglass insulation but most are from companies that sell something different.
