Fiberglass Insulation Details

Fiberglass Batt Insulation

Fiberglass is a type of flexible fiber, primarily made of glass. It has many uses, but its main purpose is to act as a commercial thermal insulator. By trapping pockets of air, it slows the spread of heat and cold.


Fiberglass batt insulation is best used between studs, joists, and beams of unfinished walls, floors, and ceilings. This is one of the most cost-effective insulation materials while still providing superior effectiveness in protecting your property from harsh temperatures.

  • Fiberglass Batt Insulation Benefits

    Aside from its budget-friendly design, fiberglass insulation also offers fire resistance, indoor sound reduction, and easy installation. Fiberglass insulation resists mold and mildew, helping protect your home’s air quality and preventing moisture damage to your home’s frame. Fiberglass insulation has long been a favorite of homeowners, contractors, and commercial builders and can be used in conjunction with other layers of moisture protection or added insulation barriers.


    • Cost-Effective
    • Easy to Use
    • Easy to Find
    • Exceptional acoustics
    • Won't absorb moisture
    • Doesn't settle or corrode
    • Lightweight and non-combustible
    • Reduces fossil fuels created by running heating systems and air conditioners

Types of Fiberglass Insulation

Fiberglass Batt Insulation

As one of the most common and cost-effective insulation options, fiberglass batt insulation comes in easy-to-use rolls in various thicknesses. It is good insulation for attics, walls, crawl spaces, ceilings and basements. Batt insulation is lightweight and can be installed quickly and affordably by professionals. It comes with or without facing, which must be placed according to the manufacturer’s specifications to resist transfer of water vapor. Both faced and unfaced varieties have an R-value from R-2.9 up to R-4.3 per inch.

Faced Fiberglass Insulation

Faced fiberglass batt insulation protects against conduction and moisture accumulation. Faced insulation has paper on one side that acts as a Class II vapor retarder when installed facing the hot-warm side during the winter months. It is most commonly installed in vertical walls, and it has a sound transmission class (STC) rating of 39, making it effective in blocking interior sound but less effective against outdoor noise.

Un-Faced Fiberglass Insulation

Unfaced fiberglass batt insulation does not have an exterior layer of paper, so its main function is to protect against conduction. It does not offer protection from water vapor or moisture and should be paired with a vapor control layer on the exterior of the building when used on outer walls. It is the most commonly used fiberglass batt in climate zones 1, 2 and 3.

Loose Fill Fiber Insulation

Loose fill fiber insulation protects against conduction and achieves an R-value of approximately R-2.5 per inch. While it is slightly less dense than fiberglass batts, loose fill fiberglass insulation offers greater ease of installation, especially in hard-to-reach areas.

Does Fiberglass Insulation Need to be Replaced?

While fiberglass insulation can last for 80 to 100 years, it may become less effective over time. After 15 to 20 years, fiberglass batts can begin to lose their structure and may also lose some of their insulating properties. Fiberglass is permeable to airflow, which may lead to “wind washing.” Dust can be blown through your fiberglass insulation, lowering the R-value and negatively impacting your insulation’s effectiveness.

Fiberglass Insulation

Proper handling of fiberglass during installation or removal is crucial to the health and safety of the installers as well as the occupants of your home. When disturbed, fiberglass releases small glass particles into the air, which can damage lungs if inhaled or can become embedded in the skin. Professional installers will employ proper PPE when handling fiberglass insulation, including gloves, skin covers, and mouth and nose coverings.


Once the fiberglass insulation is sealed and your project is finished, there are no known long-term hazards. Older fiberglass insulation sometimes contained phenol formaldehyde, which has the potential for low-grade toxic off-gassing.

 However, the formaldehyde-free fiberglass insulation used today makes the product non-toxic and much safer. Using an expert installation contractor will help ensure that proper precautions are followed when installing, removing, and handling fiberglass insulation.

I highly recommend using this company for your insulation needs. Tony was very responsive and the pricing was very fair. The workers were very prompt and efficient. Tony even showed up the day of installation to make sure the job would be completed properly. I am an extremely satisfied customer and will use them again in the future. Thank you Top to Bottom!

Top notch service. Steve is a professional and not pushy at all. Met with him and he gave me all of my options. Had them remove some blow in insulation to start and when ready they will be doing some spray foam. Highly recommend.
