How to Know if Your Atlanta Home’s Attic has Enough Insulation

Posted 08-21-13 in Air Conditioning, Heating

Adding insulation to Georgia home atticWe all know that insulation is important. Without it, keeping heat in and out during the winter and summer months respectively would skyrocket your electric bills.

However, the North American Insulation Manufacturers Association (NAIMA) states that if your home is “5 to 10 years old, you likely have one of the 46 million under-insulated homes in the U.S.” 

So how do you know if your home has enough? And if you don’t have enough, how much should you add? This article will teach you just that.

Insulation level rule of thumb

ENERGY STAR’s rule of thumb for insulation levels is this: If your insulation is evenly distributed everywhere with no low points and the insulation is just level with or below your attic’s floor joists. you should add more insulation.

How much insulation should I add?

That depends on the R-value your attic needs. R-value is a measure of insulation’s ability to resist heat traveling through it.  So, the higher the R-value, the better.

However, at some point it’s not cost effective to add more insulation. The R-value you need is based on where you live. (See image below). But on average, a home needs 10-14 inches (R-38) of insulation

R-values for Georgia

As you can see from this image from energystar.gov, Georgia is a combination of zone’s 2, 3 and 4.

Use the Department of Energy’s insulation calculator to figure out the estimated R-value your attic needs based on your zip code, house status and fuel type you use to heat your home.
