Fiberglass insulation

Fiberglass insulation is created by processing glass or sand particles to generate a fibrous thermal barrier. Some producers use recycled glass materials (up to 30%), which has substantially lessened concerns about fiberglass production's environmental impact. Fiberglass comes in rolled batt or loose-fill forms to fit the needs of diverse projects as a cost-effective approach to insulating homes and commercial buildings.

    Aside from being cost-effective, fiberglass insulation is also fire resistant, reduces indoor noise, and is simple to install. Fiberglass insulation resists mold and mildew, ensuring that your home's air quality is protected and that moisture damage to the frame is avoided. Fiberglass insulation has long been a favorite of homeowners, contractors, and commercial builders, and it can be combined with other moisture-proofing layers or additional insulating barriers.

    Your project's specifics will help you determine which type of fiberglass insulation is ideal for your needs and budget. To make an informed selection about which insulation best meets your needs, you must first understand the fiberglass insulation options available to you. 

    Because unfaced fiberglass batt insulation lacks a paper external layer, its primary role is to prevent conduction. When used on outer walls, it should be combined with a vapor control layer on the exterior of the building to provide protection from water vapor and moisture. In climate zones 1, 2, and 3, it is the most often used fiberglass batt.

    Conduction and moisture accumulation are kept at bay using faced fiberglass batt insulation. When installed on the hot-warm side during the winter months, faced insulation features paper on one side that works as a Class II vapor retarder. It's most typically used in vertical walls and has a sound transmission class (STC) of 39, which means it's good at blocking internal sound but not so good at blocking exterior noise. 


    Fiberglass batt insulation is one of the most prevalent and cost-effective insulation alternatives. It comes in easy-to-use rolls in a variety of thicknesses. Attics, walls, crawl spaces, ceilings, and basements all benefit from it. Professionals can swiftly and economically install batt insulation since it is lightweight. It is available with or without a face, which must be installed according to the manufacturer's instructions to prevent water vapor transmission. R-values range from R-2.9 to R-4.3 per inch for both faced and unfaced variants. 


    Loose-fill fiber insulation has an R-value of about R-2.5 per inch and protects against conduction. While loose-fill fiberglass insulation is slightly less dense than fiberglass batts, it is easier to install, especially in difficult-to-reach locations. Blown-in fiberglass is utilized in attics and pre-built wall cavities, and it can also be sprayed over existing insulation to boost R-value.


    While fiberglass insulation has a long life expectancy of 80 to 100 years, it may lose effectiveness over time. Fiberglass batts can lose their structural integrity and some of their insulating characteristics after 15 to 20 years. Because fiberglass is permeable to airflow, "wind washing" can occur. Dust can fly through your fiberglass insulation, lowering the R-value and reducing the efficiency of your insulation. 


    The health and safety of the installers, as well as the residents of your house, are dependent on the proper handling of fiberglass during installation or removal. When fiberglass is disturbed, small glass particles are released into the air, which can harm the lungs if inhaled or become entrenched in the skin. When working with fiberglass insulation, professional installers will use protective equipment such as gloves, skin covers, and mouth and nose shields. 

    There are no known long-term dangers once the fiberglass insulation is sealed and the project is completed. Some older fiberglass insulation included phenol-formaldehyde, which can cause low-level hazardous off-gassing. Today's formaldehyde-free fiberglass insulation, on the other hand, is non-toxic and significantly safer. 

    When installing, removing, and handling fiberglass insulation, hiring a professional installation contractor can help guarantee that all safety procedures are taken.
