How Much Attic Insulation Should a Jacksonville, FL, Home Have?

How Attic Insulation Works

The warm air in your home is either trapped in or released from the attic, since warm air naturally rises to the top. Moisture from the home gets trapped in it as well. Ventilation and sealing combined with proper insulation give you the most airflow and temperature control with less usage of heating or air conditioning.

However, the amount of insulation has to be just right for your home. If you put too little, you won’t be able to retain heat. Conversely, put too much and you’ll have an oven. You’ll also experience damage to the roof and high electric bills.

What Are R-Values?

The type of attic insulation you have in your home depends on where you live. The amount also depends on your location, and determining that comes from R-Values. R-Values are values of the thermal resistance an insulating material has, as provided by the Department of Energy.

What’s Ideal for Homes in My Region?

Jacksonville, FL, residents experience a climate of hot summers, cool winters and many wet days year-round, and temperatures typically vary from 46 to 90 degrees. Therefore, you need to have R-Values of R30 to R60 for an uninsulated attic, and R25 to R38 for adding 3-4 inches of existing insulation. These R-Values keep homes warm in winter, cool in summer and moisture-free throughout the year.
