As a homeowner, you’re always looking for the most efficient and cost-effective ways to make your home comfortable and energy-efficient. One of the best ways to achieve this is through attic insulation. Fiberglass insulation is a versatile and affordable option for many homeowners, but with all the options available on the market, is fiberglass insulation the optimal choice for your home? While Terminix only offers fiberglass insulation for crawl spaces, it is still a common choice for attic insulation. 

Choosing between the different types of insulation means considering factors like what type of insulation you need, such as batt insulation or roll insulation, and thermal performance. Whether you're looking to reduce energy bills, improve your home's noise resistance, or want extra protection to keep pests out, make an informed decision about which insulation is right for your home.

What is fiberglass insulation?

Fiberglass insulation is made up of super fine strands of recycled glass fibers. This insulation is available in three main forms: roll insulation, batt insulation, and blown-in insulation. Roll insulation is long, continuous pieces of insulation that can be cut to fit various spaces, while batt insulation is pre-cut sections designed to fit standard spaces between walls and floors. Fiberglass insulation is installed in attics, walls, and crawl spaces. Its effectiveness can be measured by its R-value, and is based on the thickness of the insulation. The higher the R-value, the better the insulation's thermal performance.

Advantages and disadvantages of fiberglass

Fiberglass insulation is popular for its versatility and affordability. It's an excellent insulator, both for temperature and sound, and its ability to come as roll insulation or batt insulation can help it adapt to a wide variety of spaces. However, fiberglass insulation also has its drawbacks. The Occupational Safety and Health Administration (OSHA) of the U.S. Department of Labor mandates that all products containing fiberglass be labeled as both a potential carcinogen and as an irritant for skin, lungs, and eyes. Fiberglass is currently classified as an animal carcinogen, not a human carcinogen. Another concern people have is the product's flammability. Because it's made of glass, the fiberglass itself won't burn, but it can melt if exposed to a hot enough heat source. Fiberglass insulation is often packed and installed with a paper shell, which can burn. Caution should be taken when working with fiberglass insulation to prevent skin irritation and the accidental inhalation of loose fibers. Exposure to loose glass fibers typically takes place when the fiberglass has been damaged or is not installed properly.

Fiberglass vs. cellulose insulation 

Fiberglass and cellulose insulation are both popular choices for attic insulation. Fiberglass insulation is made from fine strands of glass, while our cellulose insulation is made from at least 85% recycled paper. Fiberglass insulation can be blown into attics or cut to fit, but cellulose can only be blown into place or as batts. Both options can provide energy efficiency and noise reduction. Cellulose insulation can also be treated with pesticides, while fiberglass cannot. However, cellulose insulation has a higher R-value than fiberglass, making it a more practical choice for homes in any climate. Ultimately, choosing between fiberglass insulation and cellulose insulation often comes down to the specific needs of your home.
