The Environmental Protection Agency (EPA) recommends an R-value of 30 to 60 for an uninsulated attic and 25 to 38 with existing insulation in Florida, and most homes don't even come close to this value.
ENERGYSTAR
suggests an R-value of R-38 for most homes, which translates to approximately 12 inches of insulation. The first step is to go up to the attic, inspect the state of the insulation and calculate the current level of insulation. The amount of insulation you need in your attic depends on where you live.The U. S. Department of Energy Department of State outlines the insulation requirements that you must meet depending on your location. In other words, the R-value of roof insulation in the Florida building code will vary greatly from the R-value required in Maine.
Continuous insulation is used in more than 100% of the roof area and on the upper plates of the building's eaves. One type of insulation that meets these two prerequisites is polyisocyanurate or polyiso. Having adequate insulation can make your home more comfortable and energy efficient all year round. In addition to knowing the insulation requirements, another important consideration when installing insulation is the material to be used.
Now that you have an idea of the depth you need, you should measure the width and length of your attic. Having enough insulation in your attic can help you maintain a comfortable temperature throughout your house and save money on your energy bills*, as well as preventing major problems, such as ice build-up in winter. If your insulation isn't up to par and you need more, the installation can be done as a weekend DIY project or you can call a professional installer to take care of the task. This map shows the recommended levels of thermal insulation for different climate zones, based on the recommendations of the U.
Department of Energy.
