Greenfiber, the largest manufacturer of cellulose insulation, is at the forefront of insulation technology, continuing to lead the way in sustainability and investment in a decarbonized economy. Greenfiber cellulose insulation is made from up to 85% recycled paper and cardboard—higher recycled content than almost any other commonly used building material. This plant-based, or biogenic, material locks carbon into the paper for the life of the product. Couple this with low-energy manufacturing and short-haul transportation, and it's clear why Greenfiber insulation has lower embodied carbon than any other major insulation product.
In addition to preserving our environment outside, Greenfiber strives to improve the way we live inside. That's why Greenfiber believes that your home should feel like a sanctuary, a safe space for you and your family to just be. We are committed to offering insulation that does more than regulate temperature—it brings more peace, quiet, and comfort to a house while supporting the health and well-being of those who call it home. Greenfiber products reduce sound power by 60%, equalize temperatures from room to room, and qualify as fire-blocking materials.
Our goal is to build a more comfortable world by providing something that has become increasingly harder to find—SANCTUARY®.
