Difference Between Fiberglass and Cellulose Insulation

Do you need to insulate your home? Chances are, you’ve heard of fiberglass and cellulose, two insulation materials found in many homes. Which one should you use? Many homeowners aren’t quite sure how these two types of insulation are different.

Fiberglass insulation and cellulose insulation have some similarities. For instance, both can be installed in various areas of a home, including the attic and walls. But they do have a number of differences:

  • Material: Fiberglass is made of synthetic material, while cellulose consists of organic material (mainly newspaper).
  • Color: Fiberglass insulation varies in color (pink, yellow, etc.). Cellulose insulation tends to be consistently grayish in color.
  • Performance: Both perform well, but CertainTeed’s fiberglass does not absorb or retain as much moisture and is less likely to slump and settle over time.
  • R-values: The R-values of fiberglass and cellulose are different.

Cellulose and fiberglass are similar in the sense that they are both available as blown-in insulation (blown-in cellulose is also called loose-fill cellulose). Also, they both have good soundproofing qualities.
