CleanFiber Secures $28M in Series B Funding for Revolutionary Cellulose Insulation Innovation

In an exciting development for the sustainable building materials industry, CleanFiber™ has successfully secured $28 million in funding to further its mission of reimagining cellulose insulation production. The company, which was formerly known as Ultracell Insulation, was founded by experienced cellulose installers who recognized the need for innovative and eco-friendly solutions amid dwindling supplies of traditional feedstocks like old newsprint. CleanFiber specializes in high-performance insulation made entirely from recycled corrugated cardboard boxes and other clean fiber sources, positioning itself at the forefront of the green construction movement. The funding will be pivotal in scaling their operations and enhancing their patented manufacturing process, which not only embeds fire retardants for better safety but also reduces dust and contamination—major concerns within the insulation industry. As builders and homeowners increasingly prioritize sustainability without compromising on performance, CleanFiber is well-equipped to deliver superior insulation that outperforms traditional offerings, all while maintaining a competitive price point. This significant infusion of capital is expected to accelerate CleanFiber’s production capabilities, expand its reach to new markets, and foster further research and development initiatives aimed at innovating in the cellulose insulation sector. With this funding, CleanFiber is set to solidify its position as a leader in the eco-conscious building materials market, driving both environmental responsibility and economic growth.
