Which Is the Better Attic Insulation: Blown or Rolled?

Having sufficient insulation installed in your attic can make a big difference in your monthly energy usage, as a cooler attic means a lighter workload for your home’s HVAC system. If you need to have insulation installed in your attic, you might be wondering whether blown-in or roll fiberglass insulation is the better choice.

Let’s look at both options:

Roll Fiberglass Insulation

Fiberglass has long been the go-to choice for most homeowners because it performs well and is inexpensive to install. Traditionally, fiberglass installation has come in rolls or batts that can be cut to fit any space and can be installed in walls and rafters. When cut properly, the snug fit of roll insulation helps stop airflow and heat transfer. Studies indicate that batt insulation can reduce the amount of energy required to heat and cool a home by as much as 50%.

Roll fiberglass insulation maintains its effectiveness because it doesn’t settle as much as some other types of insulation, and it’s naturally fire retardant. On the downside, fiberglass rolls, even when cut to exacting standards, tend to leave gaps where air can escape.

Blown-In Fiberglass Insulation

More recently, blown-in fiberglass insulation has become the more popular option, and for good reason. The main advantage of blown-in insulation is that it provides a level of coverage that roll fiberglass can’t achieve. All those hard-to-reach corners and gaps in the attic receive excellent coverage, creating an attic that is better insulated. Blown-in fiberglass insulation also maintains its level well, which means it doesn’t settle as fast as other types of insulation.
