CleanFiber makes high-performance cellulose insulation from recycled corrugated cardboard. Our competitors make cellulose insulation from recycled newsprint but are facing rapidly dwindling supplies as readers turn online. In addition to the lack of availability, CleanFiber addresses ongoing quality issues with a competitive product using a patented liquid fire retardant process that affords cellulose installers with a super clean, low-dust, advanced carbon-negative product. Our proven process allows us to manufacture a superior product from corrugated cardboard at a lower cost than conventional cellulose insulation.
