Product Features

Sanctuary is engineered to fill tiny crevices and gaps, creating a dense, scientifically advanced barrier capable of reducing the power of sound by up to 60%¹. As cellulose insulation that can be blown-in or spray-applied, Sanctuary can be easily installed over existing insulation, and unlike batt or roll alternatives, it is engineered to fill every gap, void and hard-to-reach place without time-consuming cutting and fitting. Installed in attics, walls, ceilings and floors, Sanctuary keeps homes cooler in the summer and warmer in the winter, reducing heating and cooling costs by up to 25%2. Sanctuary has a Class 1/A fire rating, qualifies as a fire-blocking material and has been proven to be 57% better at resisting fire than most other common type of residential insulation3.

  • Promoting Wellness

    With Greenfiber insulation, we can change the way people live, sleep, relax and feel. Traditionally, insulation was considered a necessary filler, a commodity to be installed in walls and ceilings to regulate temperatures, help save energy and money, and buffer against the outside world. But we know (because we have the data to prove it) that insulation can also be an effective way to bring sanctuary back to a bustling, changing world.

  • PROTECTING OUR ENVIRONMENT

    It wouldn’t make sense to simply improve the way we live inside, if we weren’t also looking to preserve the environment outside. Greenfiber® cellulose insulation products use 13 times less energy to manufacture than fiberglass insulation⁴, and are made with postconsumer paper fiber and are free from unhealthy substances such as formaldehyde and asbestos. Our commitment to the environment is one more reason people can feel better about their choice of insulation.
