About

Greenfiber, the largest manufacturer of cellulose insulation, is at the forefront of insulation technology; continuing to lead the way with innovative products and solutions. With seventeen manufacturing facilities across the United States and Canada, Greenfiber believes that your home should feel like a sanctuary, a safe space for you and your family to just be. That’s why 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 a home. Greenfiber products reduce sound power by 60%, equalize temperatures from room-to-room and qualify as fire-blocking materials.

Greenfiber is also committed to stopping global warming and climate change through locking up carbon and removing carbon dioxide from the atmosphere. Our products are made with 85% recycled paper which keep carbon locked in for the life of the product. Along with our low-energy manufacturing and short-haul transportation, we are committed to sustainability and investment in a decarbonized economy. In 2024, Greenfiber will remove 142,256 TONS of carbon dioxide from the air

Respected for our commitment to satisfying their customer’s unique insulation needs, Greenfiber has a dedicated team of customer service representatives that offer support, as well as technicians across the country that provide installation and equipment training.
