Blown-in Attic Insulation Facts

Blown-in insulation (sometimes called blow in insulation) comes in bags and is loosely filled blotches of fiberglass that insulates your home. It largely resembles the lumps of cotton found inside pillows. It’s called blown-in insulation because it is most commonly blown into an attic through a special insulation blower, which has a long, wide hose that shoots the insulation through your attic like snow. There are three types of insulation options available for your attic: radiant barriers, blown-in insulation, and batt insulation.

What is insulation R-value?

R-value is determined by installing the number of bags per 1000 square feet to the desired height in inches when the insulation is settled and at the desired weight, determining the density. Green Energy of SA installs R-30 fiberglass blown insulation, which is 10.25 inches tall throughout your attic, with a weight of no less than .436 pounds per square foot.

The maximum that one bag can cover for R-30 insulation is no more than 65.4 square feet. Insulation is not sold by the inches, it’s sold by the amount of bags it takes to fill your attic up to the specified (R-30) R-value. Basically, the higher the R-value, the better the insulation. The R-30 insulation we use, for example, is better than R-19 insulation.

If a San Antonio insulation installer covers your attic with less than the minimum number of bags it needs, your attic will have a lower insulation R-value, which means you won’t get the same energy savings during the hot Texas summers. At Green Energy of San Antonio, we guarantee a quality job, with R-30 insulation properly installed in your attic.
