One of the major causes of losing heat during winter and retaining cool temperature during summer is the use of inappropriate attic insulation. That’s why it’s important to do an energy audit of your home particularly involving the attic. You may also use a thermal camera to check on some cool spots that are found in the attic. There might be holes that you need to fill, or it might be that you need to replace the entire attic insulation to save more.
Determining the R-Value
It is recommended that you determine the R-value of your home according to your location. This information can be derived from the Department of Energy in your region. The R-value is the insulating materials level of resistance to heat flow. This is measured by the thermal resistance which is commonly known as R-value. It would be better for any home to have a higher R-value. This information will also help you determine the type of attic insulation in Florida you need. Generally, the ideal R-value for any home is between R-3- to R-49. In a cold climate location, it can rise up to R-60.
Types of Insulation
Blanket Insulation
This is the easiest type of attic insulation. This is available as batts or rolls and it’s good for a DIY insulation project. It is available in different types namely fiberglass, natural fibers, mineral wool, and plastic fibers. This is the type of insulation for attics that have standard space beams and joints.
Sprayed Foam Insulation
This is a more expensive type of insulation that can be done on your own. It is also the type that has the highest R-values. It has two types the open-cell and closed-cell. Both types are made of polyurethane.
Loose-Fill Insulation
This type of insulation is perfect for attics that have limited headroom with multiple obstructions like cross-beams and vents. This is available in fiberglass, mineral wool, and cellulose. The most effective material of all is cellulose. This type of insulation can be bought at Home Depot or from online outlets.
Concrete Block Insulation
This type of insulation requires the person installing it to have specialized skills. Insulating concrete blocks are often stacked without mortar and they are often surface bonded. Some of the materials used are foam beads and form boards.
Reflective System
This can also be a DIY task. This is appropriate for framing at standard spacing. This is the most effective attic insulation to prevent downward flow of heat, and its effectiveness relies on the spacing. This can be done using the following materials: plastic film, Foil-faced kraft paper, cardboard, or polyethylene bubbles.
Fiber Insulation
This is the type of attic insulation that can withstand high temperatures. It is highly applicable in ducts that are in unconditioned spaces. This type of insulation is made of fiberglass and mineral wool.
