When it comes to insulating an attic in Florida, aerosol foam insulation is the most efficient and effective option. With an impressive R-value of six to seven per inch, it is the best choice for the hot and humid climate of the Sunshine State. However, if you're looking for a more budget-friendly option, blown fiberglass insulation is also a viable choice. No matter which type of insulation you choose, it's important to understand the basics of attic insulation and how to measure its thickness.
The Department of Energy's insulation fact sheet provides information on how to determine the R-value using this technique. Additionally, Table 1 may be helpful in understanding the recommended R-value for different types of insulation. When selecting an insulation product, consider factors such as space availability, weight per volume, cost, ease of access, and whether you are building a new house or improving an existing one. Aerosol foam insulation is a great choice because it functions as both an insulating material and an air barrier.
However, its high cost may be prohibitive for some homeowners. Blown fiberglass is another option for insulating attics in hot and humid climates like Florida. It has a recommended R-value of R-2.5 per inch and is relatively inexpensive compared to aerosol foam insulation. However, it does not prevent moisture from passing through, so if you live in a humid climate or experience high humidity (as in most parts of Central Florida), foam insulation for open-cell attics may not be the best option. It's important to consult an expert before deciding which product best fits your needs.
Installing the right type of attic insulation is crucial for homeowners who live in hot and humid climates like Florida. We offer other types of insulation for your home, such as rigid foam plates, non-stick insulators and fiberglass blown insulation.
