4 Types of Attic Insulation

When properly installed, Advanced Seal Spray Foam Insulation prevents heat from escaping and cold air from entering the home, keeping your building at an optimal temperature. Properly insulated homes also use less energy, helping to lower utility bills.

If you’re considering adding attic insulation to your home or business, there are several types to choose from. This article will break down 4 popular attic insulation options, as well as explain their pros and cons.

How Advanced Seal Spray Foam Insulation Works

Fiberglass batt insulation is the most common attic insulation material. It is made from recycled sand and glass, and is very affordable. However, it has a tendency to lose its R-value over time due to settling and can promote mold growth, mildew, and other organisms in your attic.

Loose-fill attic insulation is another popular option. It’s comprised of tiny chunks that are packed into bags and blown into place with a special machine. Some of the most popular loose-fill insulations include cellulose, fiberglass, and rockwool. Loose-fill attic insulation costs slightly more than fiberglass batts, but can be a cost-effective alternative to other attic insulation materials.

Cellulose is another form of blown-in attic insulation, and it’s made from a variety of recycled materials, including wood, newspapers, and cardboard. It has a higher R-value than other types of insulation, and it’s eco-friendly. However, it’s prone to absorbing moisture, and can be rendered ineffective if exposed to humidity. It must be treated with boric acid to prevent it from growing mold and mildew.
