Is Fiberglass Insulation Right for You?

April 20, 2021

Insulation is an important feature in all Northern California homes. Whether you’re building a new house or considering replacing your current insulation, you have a choice when it comes to the material you use. While fiberglass insulation, in either batt or loose fill options, is a popular choice, it’s not always the best one. Here are the major pros and cons of fiberglass insulation and how you can tell if it’s right for your home.

Thermal protection

When considering the pros and cons of fiberglass insulation for your Northern California home, one of the major benefits is its thermal protection value. Both fiberglass batt and loose fill insulation can provide up to R-4.3 per inch, but only when the insulation is installed correctly. It takes professional installation, starting with comprehensive air sealing, to ensure that fiberglass insulation maintains its level of thermal protection throughout the years. In some cases, a technician will have to “top up” the insulation to maintain its protective value. When installed correctly, your fiberglass insulation can have a higher R-value than some types of spray foam insulation.

Air seal

One of the cons to choosing fiberglass insulation is that creating an airtight seal is a bit more complicated when compared to spray foam insulation, but it can be done. Spray foam creates both an air barrier and an insulation barrier all at once. It is considerably more expensive than fiberglass materials, though. Again, if you choose to go the more affordable route and select fiberglass as your insulating material, make sure the installation is done by a seasoned professional. The technician will install a separate air barrier to keep your home airtight.

Moisture barrier

Insulation needs to be able to resist moisture, and in areas like an attic cavity, moisture accumulation can be prevalent. In considering the pros and cons of fiberglass insulation, one of the major drawbacks is that fiberglass batts don’t create a moisture or vapor barrier on their own. If you rely on the services of a professional insulation technician, though, they’ll make sure to install a separate barrier that will keep your attic free from the damaging effects of moisture.

Fire resistance

A key benefit to choosing fiberglass as your insulating material is that it can either be naturally fire resistant or treated with a fire retardant to protect your home in case of fire. Always rely on the expertise of a trained professional for peace of mind that your insulation won’t catch fire. Spray foam, on the other hand, requires a special thermal barrier material placed over the insulation. It’s an extra cost that you don’t have to pay for if you choose a fiberglass option.

Understanding the pros and cons of fiberglass insulation can help you make the right decision when it comes to choosing insulation for your Northern California home. Always rely on the professional expertise that only a trained insulation installation expert can provide.
