What You Should Know About Attic Insulation

Properly insulating the space in your attic can save you money on your electric bill every month. Even in Florida, your winter heating bill can be reduced if you have the right kind and amount of attic insulation. In fact, the federal Department of Energy and the EPA estimate you can cut 10% to 15% off your energy bills just by installing the right kind and amount of attic insulation. Knowing what to choose, and how much to use, however, can be a little tricky.

Types of Attic Insulation

There are several kinds of insulation you can use in your attic. Blanket insulation (also called batt) comes in large rolls and is available in fiberglass, natural fibers, plastic fibers and mineral wool. The rolls are sized just right to fit between standard beams that run across the attic, making it easy to install, especially if you do not have a floor installed.

Loose fill insulation comes in bags and is blown into place using a special machine. It can also be poured and spread manually, but that takes longer. For attics without standard spacing between the beams, it allows you to place the insulation anywhere you like. This is also good when you have obstructions in the space that you need to work around, or small attics with low head space. We strongly recommend hiring a professional to install insulation in this way, as they will have the right equipment and knowledge to do it properly.

Cellulose insulation is made of recycled paper treated to be resistant to fire and insects and is generally blown in. Mineral wool is made from rock or recycled slag fibers.

What is an R-Value For Insulation?

The R-Value is a rating for insulation based on the type and thickness of the material. A higher R-Value will perform better than a lower value. Different R-Values are recommended depending upon the area where you live and the climate there. In Northeast Florida, the Department of Energy recommends attics be insulated with an R-Value of R30 to R49. Crawlspaces should use R13 – R19 and walls range from R13-21, depending upon the space between beams. You can add more energy efficiency by adding a second layer of insulation in your attic.

Use Caution With Fiberglass Insulation

If you are installing insulation yourself, use caution with the rolls of fiberglass. It can irritate your lungs and skin because it is made with thin strands of glass. It can easily get into your air vents and circulate through your home, as well, if it is not properly sealed. Using gloves, a face mask, and other protective clothing will help prevent irritation from contact with the fiberglass.
