When it comes to insulation requirements in Florida, it's important to understand the R-value. This resistance, or R-value, measures the performance of the insulation over time by measuring the resistance to heat flowing through the insulation. In residential buildings, the insulation of framed walls must meet or exceed R-13, while block walls must have interior insulation of at least R-7, 8 and external insulation of R-6.The roof insulation must be much higher, with R-30, and a raised floor must have at least R-13. In addition to knowing the insulation requirements, it's also important to consider the material used. 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.
However, it's important to note that the way in which the insulation is installed is almost as important as the R value itself. Additionally, the overall R value of a wall or roof will be somewhat different from the R value of the insulation itself due to thermal bridges. Aerosol foam insulation is best used in areas that are already insulated but need additional levels of insulation to meet requirements or maximize energy efficiency. To help you find the right amount and type of insulation for your home, here are some guidelines for Florida.
