What Are The Requirements For Attic Insulation In Florida? What are the requirements for attic insulation in Florida? If your attic is under-insulated, poorly vented, or full of air leaks, your AC may be working harder than it should in Florida’s hot-humid climate. That matters because attic heat gain can raise cooling loads by as much as 30%, and insulation upgrades can reduce cooling energy use by roughly 10% to 20%, according to Energy.gov. https://greenserviceinsulation.com/home-improvement/what-are-the-requirements-for-attic-insulation-in-florida/
