About

CleanFiber™ makes high-performance cellulose insulation from recycled corrugated cardboard boxes and other clean sources of high quality fiber. The company was formerly known as Ultracell Insulation and was founded by veteran cellulose installers, who wanted to see this industry thrive despite declining supplies of old newsprint (which is the primary feedstock of the industry today). CleanFiber's product provides lower dust, lower contamination, and better coverage that competitive product. Our unique and patented process for embedding fire retardants in our product allows us to deliver a superior product at a cost-competitive price
