What is Loosefill Blown-In Fiberglass Insulation?

Blown-in fiberglass is made of tiny glass fibers that are blown into an attic or wall cavity using a high-powered blower. The result is a soft, even layer of insulation that fills gaps and irregular spaces—perfect for older homes, attics, and retrofits.



It offers great thermal resistance and helps slow down heat transfer between living spaces and unconditioned zones like the attic.

FAQ

  • Is blown-in fiberglass insulation better than spray foam?

    Blown-in fiberglass is more affordable and quicker to install, especially for attic floors. Spray foam offers better air sealing and higher R-value, but at a higher cost. We can help you decide which fits your needs best.

  • How long does blown-in fiberglass insulation last?

    When installed correctly, blown-in fiberglass can last 30 years or more without settling or losing effectiveness.

  • Can blown-in fiberglass be added over old insulation?

    Yes, in most cases you can top off existing insulation with new blown-in fiberglass to improve performance and meet updated energy codes.

  • Is fiberglass insulation safe for my home?

    Modern fiberglass insulation is safe, non-combustible, and does not promote mold growth. Proper installation prevents airborne fibers from entering the home.

  • How do I know if my attic needs more insulation?

    If your attic has less than 10–14 inches of insulation, or if you experience uneven temperatures or high energy bills, a blown-in insulation upgrade may be needed. We offer free assessments.
