• Greenfiber

  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.
