Florida Building Code (FBC) requires a minimum insulation R-value of **R-38** for attic ceilings in Climate Zone 2 (South Florida) and **R-38 to R-60** in Climate Zone 2A (Central and North Florida, including Volusia, Flagler, and St. Johns Counties).
These requirements apply to new construction and substantial renovations. However, even if you're not doing a full renovation, upgrading insulation in an existing home to meet or exceed code is strongly recommended — and often qualifies for energy efficiency tax credits.
Common code requirements for Florida attics include: minimum R-38 blown-in or batt insulation on the attic floor, proper vapor barriers in high-humidity areas, and air sealing around all penetrations (wiring, plumbing, HVAC ducts) before insulation is added.
Florida Attics installs all insulation in compliance with current FBC requirements. Every job includes documentation of installed R-value for your records — useful for insurance purposes, permit compliance, and future home sales.
