NOW WELLNESS CAN
START IN YOUR WALLS

Installed in attics, walls, floors and ceilings, Sanctuary® by Greenfiber® can bring peace, quiet and comfort to your home.

Sanctuary by Greenfiber outperforms other types of insulation in one critical way after another. Plus, it offers advantages you’ve probably never thought about.

  • REDUCE SOUND POWER BY 60%

    Where air flows, sound follows. Sanctuary is engineered to fill the tiny joints, crevices and gaps hidden within your attic, walls, floors and ceilings. Highly effective as sound insulation, it serves as a scientifically advanced barrier capable of muffling sounds that typically infiltrate and reverberate through our homes. Proven to reduce the power of sound by up to 60%1, Sanctuary is specifically designed to keep the racket of the outside world out and ensure that our most private spaces remain private.

  • ADD COMFORT AND SAVE ENERGY

    When used as attic insulation or installed in walls, ceilings and floors, Sanctuary will keep your home cooler in the summer and warmer in the winter. Designed to regulate temperature room by room, when installed in exterior walls, Sanctuary can also reduce heating and cooling costs by up to 25%.²

  • ENJOY PEACE OF MIND

    With a Class 1A fire rating, Sanctuary contains active fire-resistant materials and is 57% better at resisting fire than most other common types of residential insulation. Two to three times denser than fiberglass, Sanctuary qualifies as a fire-blocking material, and in a large-scale fire test, it lasted 60% longer than fiberglass batts³ — making Sanctuary the best choice to protect you and your family.

  • BE GOOD TO THE ENVIRONMENT

    Sanctuary requires 13 times less energy to manufacture than fiberglass insulation⁴, is made with 85% postconsumer paper material and is free from unhealthy substances such as formaldehyde and asbestos.

  • INSTALL IT WITH EASE

    Since Sanctuary can be blown-in, it doesn’t require time-consuming cutting and fitting. Plus, it can be blown into small, tight, difficult-to-access spaces, providing far better coverage, and it can be applied directly over existing insulation. Each bag of Sanctuary is easy to handle and break up for loading into Greenfiber blowers. Our blowers can be rented from your local Greenfiber retailer and require no training or special skills to use.
