    The advanced building system that sets homes apart
  • The right combination for enhancing wellness

    Greenfiber insulation is engineered to fill the tiny joints and gaps hidden within walls, floors and ceilings, creating a dense, scientifically advanced barrier. It’s coupled with market-leading Trane technology to create homes that are quieter, warmer, cooler, cleaner and more hygienic — homes that are more comfortable and appealing at every level. 

    The right combination for enhancing wellness
  • Quieter homes are healthier homes

    Greenfiber cellulose insulation provides a 60% reduction in sound power² thanks to its high density and ability to fill gaps and voids. Coupled with the advanced, quiet technology integrated into every Trane product, it promises benefits well beyond a good night’s sleep. Research shows that noise exposure may contribute to 14% of hypertension cases and 9% of high cholesterol cases.³ And $3.9 billion each year could be saved in the U.S. in treating cardiovascular diseases by lowering environmental noise by 5 decibels.⁴

    Quieter homes are healthier homes
  • Healthier homes bring comfort, health and efficiency together

    Cellulose is denser and has better resistance to airflow than conventional insulation, so it works more efficiently as insulation. Together with Trane’s market-leading CleanEffects™ whole-house infiltration system, it creates a tighter home that:

    • Guarantees consistent temperatures from room to room that differ by no more than 3 degrees from the thermostat set point.⁵
    • Is 40% more energy efficient.⁶

    In addition, Trane’s CleanEffects system:

    • Is certified by the Asthma and Allergy Foundation of America to remove up to 99.98% of allergens from filtered air and can reduce dust by up to 50%.
    • Offers advanced humidity control.
    • Delivers clean air throughout the home up to 100 times faster than a standard 1-inch air filter.

    Healthier homes bring comfort, health and efficiency together
  • 1-hour firewall means safer homes⁷

    Greenfiber is 57% better at resisting fire.⁵ Since it’s two to three times denser than fiberglass and treated with fire-retardant additives, our cellulose qualifies as a fire-blocking material and offers more time to react in emergencies.
