In general, current best homebuilding practices indicate an R-30 to an R-38 for attic insulation. The Florida Building Code identifies two distinct “climate zones”. The best type of attic insulation for Florida's hot and humid climate is spray foam. Closed cell spray foam has an impressive R-value in the range of six to seven per inch. Other suitable types of attic insulation for Florida include blown fiberglass, blown cellulose, and fiberglass blocks.
Installing the right type of attic insulation is crucial, especially for homeowners who live in hot, humid climates like Florida. Blown fiberglass is a type of loose fill insulation that is efficient when used to insulate attics in hot, humid climates such as Florida. Because of Florida's warm, humid and humid environment, the best insulation for the attic should be durable and, ideally, completely seal the attic to prevent warm air from entering. Its R value is higher than that of open-cell aerosol foam and other insulating materials, making closed-cell aerosol foam one of the most reliable insulators on the market.
If you're a resident of Florida, you probably know the role that proper attic insulation plays in keeping your home warm during the winter and cool during the summer. Blown fiberglass installed in the attic has an R value of 2.2 per inch, so 12 inches would give it an R value of 26.4 in an attic installation project. If you are going to install insulation in an attic in Tampa, it should have a higher R value than wall insulation, since heat rises naturally and, in general,, escapes through the attic. The insulation has a fairly recommended R value of R-2.5 per inch and is relatively inexpensive compared to aerosol foam insulation.
And while spray foam is undoubtedly the best insulation product, its high cost makes it less desirable for homeowners looking to insulate their attics on a budget. While the best type of insulation for attics depends largely on personal preferences and budget, the effectiveness of aerosol foam insulation cannot be ruled out, especially in a hot, humid state like Florida. When it comes to aerosol foam insulation, it is highly recommended to outsource experienced professionals who know the ins and outs of attic insulation. If you know that some insulators withstand heat flow better than others, it may be tempting to buy the insulation with the highest R value and call it a day.
Although not as dense as its closed counterpart, open-cell insulation is still very useful as attic insulation. When properly installed by certified experts, aerosol foam insulation fills every space in the attic, making it an effective air barrier. You don't need to have experience insulating attics or walls to install a batch of fiberglass blocks.
