Energy Star's recommended insulation map for homes shows that most of Florida is within Zone 2.This area has a recommended R-value of 30 to 60 for an uninsulated attic, R25 to R38 for an existing insulated attic, and R13 to R19 for the floor. The R-value of blow insulation ranges from 2.7 to 3.3 per inch and depends on the material used and whether it is loose or densely compacted. It should be noted that, while both blown blocks and blocks can be made from the same materials, the R-value depends on density, meaning that blown fiberglass will have a lower R-value than fiberglass blocks. This resistance, or R-value, refers to the performance of the insulation by measuring the resistance to heat flowing through the insulation over time.
Blown fiberglass installed in the attic has an R-value of 2.2 per inch, so 12 inches would give you an R-value of 26.4 in your attic installation project. Attic insulation is critical because more heat passes per square foot through the roof than in any other structure in a home. Block insulation is the only insulation that requires additional consideration when it comes to working around items such as electrical boxes, desks, ductwork, and pipe vents.

Types of Insulation
.When it comes to selecting the best R-value insulation for your attic in Florida, there are several factors to consider.The choice of insulation depends on the space you have, the apparent density of the materials (weight by volume) so that the ceilings do not sink with the additional weight, the ease of access to the space, the money you can spend, how easy it would be to replace the insulation if you had a leak in the ceiling or wall, and whether you are going to build a new house or improve an existing one. If you're not sure what type of insulation already exists in your home, take a sample to an insulation expert. Blown insulation is more versatile than blocks, as it can be used not only to insulate walls and attics, but because of its nature, it can also be used to seal air leaks, such as wiring holes, pipe ventilation ducts, open ceilings and attic hatches. If you are building a new home, you can consider installing insulation at the bottom of the roof covering and sealing the attic space to create an “unventilated attic”.Make sure that the roof or walls can support the additional weight derived from the additional insulation before installation. If you're installing attic insulation in Tampa, you'll need a higher R-value than wall insulation, as heat rises naturally and usually escapes through the attic.
It's very important to understand that how the insulation is installed is almost as important as the R-value. You can measure the thickness of the attic insulation with a ruler and multiply the number of inches by the R-value of that particular insulation to get an insulation rating. Total attic insulation, block insulation, home insulation, office insulation, soundproof spray foam insulation. In two-story houses, floor beams are not always sealed from adjacent attic spaces over single-story spaces and attic air is right next to the roof. Once you've determined your area and where the insulation is going to be placed, you look at different options and types of insulation. As an expert in this field I recommend considering all factors before making a decision on which type of R-value insulation is best for your attic in Florida.
Make sure that you take into account all aspects such as cost effectiveness, ease of installation and access to space when selecting your ideal option.
