CleanFiber is a mid-sized producer in the wholesale building materials sector, based in Buffalo, New York. It manufactures high-performance cellulose insulation derived from recycled corrugated cardboard and other clean fiber sources, designed to deliver lower dust, less contamination, and better coverage than typical products. The company was founded by veteran cellulose installers who sought to revitalize the industry amid shrinking supplies of old newsprint, and it uses a patented process to embed fire retardants in its insulation to offer a cost-competitive solution.

CleanFiber operates within the wholesale building materials market and provides insulation products for projects that require reliable, sustainable solutions. In January 2025, Sami Rahman was appointed president to lead innovation and growth, following the departure of longtime CEO Jon Strimling earlier in the month.
