When it comes to insulating an attic in Florida's hot and humid climate, spray foam insulation is the best option. With an impressive R-value of six to seven per inch, closed-cell spray foam is one of the most reliable insulators on the market. Other suitable attic insulation materials for Florida include blown fiberglass, blown cellulose, and fiberglass blocks. Insulation is a material that slows or inhibits the flow of heat from one area to another.
Fiberglass or mineral wool (also known as rockwool and sunken wool) are common types, while cellulose insulation is an environmentally friendly option that is inserted into wall cavities. Spray foam insulation is an ideal choice if you need to add insulation to existing areas and around obstructions. The type of insulation and installation method you use can favor or harm your energy efficiency efforts, so it's worth consulting with an expert before deciding which product best suits your needs. Open-cell foam attic insulation may not be the best choice for the attic in humid climates, as it does not prevent moisture from passing through. Many DIYers try to save money by installing electric baseboard stoves and an air conditioning unit in the windows to heat and cool their new attic. Although not as dense as its closed counterpart, open-cell insulation is still an excellent insulator for attics.
One of the main benefits of spray foam insulation is that it also functions as an insulating material and an air barrier. And while spray foam is undoubtedly the best insulating product, its high cost makes it less attractive to homeowners looking to insulate their attics on a budget. An ideal solution for insulating an open loft-like space is loose filler insulation. You don't need to have experience insulating attics or walls to assemble a batch of fiberglass blocks. An insulation professional will know what type and how much insulation your home will need and local building codes. If you're looking for a reliable way to protect your home from Florida's hot and humid climate, spray foam insulation is the way to go.
It's highly recommended to hire experienced professionals who know the ins and outs of attic insulation. If you're not sure what type of insulation to install in your home, an insulation contractor can help you decide.
