Why should you switch?

Jobs will just go smoother when you blow Greenfiber into any new construction or retrofit space, including hard-to-reach areas. Using our blow-in cellulose is the easiest way to keep up with constantly changing codes and keep on moving.

  • A better fit for your needs.
    Retrofit without the fuss

    Retrofit without the fuss

    It’s easy to blow Greenfiber over existing insulation without removing the old, letting you reach the necessary R-value with ease. In addition, our cellulose insulation fills every gap, void and hard-to-reach place without time-consuming cutting and fitting.

    Greenfiber can also be dry blown into walls and floors if desired. Plus, it’s easily sprayed above non-woven netting fastened to rafters in attics, cathedral ceilings or floor joists in basements to insulate floors above. It can also be sprayed behind non-woven netting fastened to studs in exterior walls, garage walls and knee walls.

  • Let’s hear it for quiet.
    Absorbs sound.

    Absorbs sound.

    Greenfiber helps you tune out your neighbor’s lawnmower and the garage band next door. Where air flows, sound follows. But because GreenFiber is so much denser than fiberglass and blown in to fill every space, it provides “superior noise transfer reduction” through floors and walls, which is a technical way of saying it does a great job of blocking sound.

    Unmatched Fire Resistance

    Unmatched Fire Resistance

    With a Class 1 fire rating, Greenfiber is 57% better at resisting fire than most other common types of residential insulation. Other forms of insulation don't contain active fire-resistant materials. In addition, its density is two to three times greater than fiberglass, and qualifies Greenfiber as a fire-blocking material. In a large-scale fire test, Greenfiber lasted 68 minutes – 60% longer than fiberglass⁴ batts – making Greenfiber the best choice to protect your customers and the people they love.
