We’re excited to offer you a new way to elevate your customers’ home experience, to differentiate yourself from the competition and to build homes that promote happiness and well-being: Sanctuary Homes by Greenfiber.

SANCTUARY IS THE BETTER WAY

  • Managing Sound and Improving Privacy

    Sanctuary by Greenfiber offers market-leading sound insulation products that can reduce sound power by 60%¹ and are perfect for ensuring every room in the home remains peaceful and quiet.

  • Making More Comfortable Homes

    By installing our cellulose insulation by either dense-pack or spray application, you’ll be building a home with more consistent temperatures from room to room and floor to floor.

  • Providing Peace of Mind

    Sanctuary qualifies as a fire-blocking material, and in a large-scale fire test, it lasted 68 minutes – 60% longer than fiberglass batts.²
