The residential insulation map recommended by Energy Star shows that most of Florida is within Zone 2.This zone has a recommended R value of 30 to 60 for an uninsulated attic, from R25 to R38 for an existing insulated attic, and from R13 to R19 for the floor. Polyisocyanurate (ISO plate), extruded polystyrene (XPS or blue board), expanded polystyrene (EPS or bead board) or other materials are generally found in the form of a rigid board. These boards are lightweight and usually have an R value of 4 to 7 per inch. Aerosol foams, such as urethanes and polykinene, are also available with R values 3 to 6 per inch.

If you're building a new house, you might consider installing insulation on the underside of the roof cover and sealing the attic space by creating an “unventilated attic”. This resistance, or R value, refers to the performance of the insulation by measuring the resistance to heat flowing through the insulation over time. In addition to knowing the insulation requirements, another important consideration when installing insulation is the material to be used.
The effectiveness of an insulated wall or ceiling also depends on how and where the insulation is installed. 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. It is very important to understand that the way the insulation is installed is almost as important as the R value. 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 difficult to access.
In addition, for businesses and consumers concerned about false advertising, inadequate installation, and other insulation-related considerations, there is a Federal Trade Commission rule designed to protect them (Title 16, Business Practices, Part 460, Labeling and Advertising of Home Insulation). To help you find the right amount and type of insulation for your home, here are the insulation requirements in Florida. 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. The choice of insulation depends on the space you have to insulate it, the apparent density of the materials (weight per volume) so that the roofs don't sag with the additional weight, how easy it is to access the space, how much money you can spend, how easy it would be to replace the insulation if you had a roof or wall leak, and whether you are building a new house or improving an existing one. If you're not sure what type of insulation already exists in your home, take a sample to an insulation expert.
Attic insulation is critical because more heat per square foot passes through the roof than any other structure in the house.
