Insights

Expansion momentum CleanFiber is in a high-growth phase with recent headcount expansion, a major leadership hire, and multi-year financing that supports national plant expansion. Tailor outreach to strategic accounts in regions poised for new installs and highlight scalability, supply certainty, and deployment timelines.

DOE funding leverage The company secured significant DOE grants and broad financing (20M grants in 2024, total capital of 75M for expansion). Position opportunities around projects that align with energy efficiency, recycled feedstock insulation programs, and incentives that favor high-performance cellulose insulation.

Competitive edge CleanFiber emphasizes low dust, low contamination, better coverage, and embedded fire retardants for cost-competitive performance. Use cases that demand superior indoor air quality, reduced installation waste, and code-compliant performance can differentiate CleanFiber from incumbents.

Leadership and vision With a new president focused on innovation and growth and a former CEO stepping down, there is an opportunity to position the product roadmap around reliability, supply-chain resilience, and strategic partnerships with builders, distributors, and insulation installers.

Market positioning Recognized as a fastest-growing manufacturing company and operating in a mid-size market segment, CleanFiber can target mid-market builders and regional distributors seeking scalable, sustainable insulation solutions with strong total-cost-of-ownership benefits and rapid deployment potential.

Wholesale Building MaterialsNew York, United States51-200 Employees

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.
