Attic Insulation: Good, Better and Best

Blown-in insulation being installed in an attic
When it comes home insulation, the first area that usually comes to mind is the attic. Airflow in buildings moves from ground to sky, naturally pulling conditioned indoor air up and out of the structure. By keeping conditioned air inside your home you can also reduce wear and tear on your heating system and help keep energy bills in line.

There are three common methods used to insulate attics – blown-in fiberglass, blown-in fiberglass with air sealing, and spray foam insulation. Here’s what you need to know about each:

Blown-in Fiberglass
Insulating attics with blown-in fiberglass insulation is a quick and easy way to add R-value. This is a basic method of attic insulation and a cost-effective option to upgrade attics in existing homes or insulate attics in new homes.

Blown-in Fiberglass with Air Sealing
Combining blown-in fiberglass insulation with air sealing dramatically increases a home’s energy efficiency. This method helps keep conditioned air inside the home and adds R-value. In an existing home, attic insulation is removed and penetration points around the attic floor are sealed. After air sealing is complete, a fresh blanket of blown-in fiberglass insulation is installed. In a new home, penetration points around the attic floor are sealed before blown-in insulation is installed.

Spray Foam Insulation
Installing spray foam insulation in the attic of a new or existing home provides optimal energy protection. In an existing home, insulation is removed from the attic and spray foam is installed along the roofline. In a new home, spray foam insulation is installed along the roofline as part of the construction process.

Proper attic insulation combined with air sealing is one of the most cost-effective ways to save money on energy bills.
