Types of Attic Insulation for Hot Climates
There are several different factors to consider when choosing the types of attic insulation you will use for a structure. You must consider the climate that you are in and what will be most energy efficient. The two basic types of attic insulation that can be used are rolled insulation and blown-in attic insulation. When installing attic insulation in warmer climates either type can be used. The most important factor for installation in a warmer climate is the addition of a radiant barrier to whichever type of insulation that is selected.
Radiant Barrier
Radiant barrier is a material used in conjunction with attic insulation to block radiant heat and reflect heat at the surface to increase efficiency of attic insulation. Radiant barrier is a foil that is placed between the attic floor and the insulation. Using a radiant barrier is especially important in a warmer climate because of the temperature that can be reached in the attic. The barrier foil blocks the heat during warmer weather and keeps heat in during the colder month to provide a year-round solution for energy efficiency.
Rolled-in Insulation
Rolled insulation is more expensive than blown-in insulation, but is easier to work with because it is laid down piece by piece. Rolled-in insulation is most commonly made of fiberglass, but can be found in cotton fiber as well.
The advantages of using rolled-in insulation is that it is easy to install and easy to remove.
