Comparing Insulation

Different insulations are made from fundamentally unique materials, and not all insulations with the same thermal resistance value perform equally in the real world. Offering superior performance and a long lifespan at an affordable price, blown-in cellulose insulation is a top home insulation choice.

The Benefits

  • Applied using a blown-in process, cellulose has an average thermal resistance value of R-3.2 per inch. 
  • Fiberglass, by comparison, offers an average thermal resistance value of R-2.2 per inch. 
  • Cellulose is denser and has better resistance to airflow, so it works more efficiently as insulation.

Cellulose vs Fiberglass

When insulating your home, fiberglass and cellulose are used most often. Fiberglass is available in rolled batting or blown forms, while cellulose is only available as a blown material.

While both cellulose and fiberglass insulations can attain a R-30 thermal insulation rating, cellulose has superior insulating properties. Cellulose achieves a R-30 rating with an average 8.1-inch thickness, whereas fiberglass needs roughly an average 12-inch thickness to obtain the same performance. Cellulose is far more effective than fiberglass per square inch, which can save money by increasing a home’s energy efficiency.

Cellulose insulation that has been properly installed does not settle, maintains its energy-saving abilities over time and does not corrode steel, copper and aluminum. Also, cellulose insulation resists rot, decay, mildew and mold. The material is soft, non-flammable, non-toxic, safe to the touch and does not itch.

Contact with fiberglass, however, can cause itching and irritation. Rodents can nest in fiberglass insulation, which does not resist insects, mold and mildew. Made from rigid glass fibers, this insulation can melt during a fire.

Another benefit of cellulose home insulation is environmental stewardship. It has the highest post-consumer recycled content, with an average of 75 to 85 percent. Cellulose insulation is manufactured from any cellular plant source, including corncobs, sisal and sawdust but most often recycled products like newspapers, cardboard, office paper and other waste paper products.
