Batt Insulation for Your Attic

Batt insulation is made of pre-cut pieces of fiberglass or other materials that fit snugly between the joists in your attic. It’s typically easy to install and can be done DIY-style without any special equipment. One downside of batt insulation, however, is that it can leave gaps and spaces around electrical wiring or other obstacles in your attic, which can lead to heat or cooling loss.

Fiberglass Blown In Insulation

Blown-in insulation, on the other hand, is made of tiny pieces of fiberglass or other materials that are “blown” into your attic space using a special machine. This type of insulation provides a much tighter seal than batt insulation, which means there’s less chance for heat loss. Blown-in insulation can also be used to fill small spaces and nooks around electrical wiring and other obstacles, making it a more versatile option overall. It can even be used to insulate walls in older homes, by being blown in through small holes in the wall cavity.
