Blown-in insulation is usually made of fiberglass or cellulose and is blown into the attic space using specialized equipment. Batt insulation, which is typically made of fiberglass or rock wool, is comprised of pre-cut panels that are installed between the attic joists. Spray foam insulation is a liquid that is sprayed into the attic space and quickly expands to fill any gaps or voids.

Attic Insulation Materials:

The most common types of materials used for attic insulation are fiberglass, cellulose, rock wool, and spray foam. Fiberglass insulation is made of tiny glass fibers and is a popular choice due to its affordability and effectiveness. Cellulose insulation is made from recycled materials like newspapers and cardboard and is great for filling small gaps. Rock wool insulation is made from rocks and minerals and is great for its fire-resistant properties. Spray foam insulation is a newer material that is becoming more popular due to its effectiveness at sealing air leaks and gaps.


R-value is a measure of insulation’s ability to resist heat flow. The higher the R-value, the more effective the insulation is. The recommended R-value for attic insulation varies depending on where you live, but ranges from R-30 to R-60. The best way to determine the recommended R-value for your attic is to consult a professional insulation contractor or the Department of Energy’s guidelines.

Now that you understand the different types of insulation, materials, and R-values, you can make an informed decision about which type of attic insulation is best for your home.
