In general, current best homebuilding practices indicate an R-30 to an R-38 for attic insulation. The Florida Building Code identifies two distinct “climate zones”. ENERGYSTAR recommends an R value of R-38 for most homes. This translates to approximately 12 inches. of insulation.
If you don't have enough, use a measuring tape to measure the depth of insulation in your attic. Blow insulation, also known as loose fill insulation, is one of the most popular insulation systems, as it is the perfect choice for attics and small spaces that are difficult to access. If you are installing insulation in an attic in Tampa, it should have a higher R value than insulation on a wall, since heat rises naturally and usually escapes through the attic. We offer attic insulation installation, air sealing and insulation removal services to help you reduce your home's energy consumption and maintain a consistent temperature.
Blown fiberglass installed in the attic has an R value of 2.2 per inch, so 12 inches would give it an R value of 26.4 in your attic installation project.
