## About

Founded in 2013 by Daniel Thompson, Jonathan Strimling, and Robert Hupper, and based in New York, US, CleanFiber Inc., formerly known as UltraCell Insulation, operates as a manufacturer of cellulose insulation for the construction industry. In October 2024, CleanFiber Inc. received USD 20 million of grant funding from new investor U.S. Department of Energy.

CleanFiber offers cellulose insulation products made from recycled corrugated cardboard and other clean sources of fiber designed to provide high quality and low dust and contamination levels to the construction industry. The company's proprietary process infuses an all-borate, liquid fire retardant directly into the fiber walls, resulting in low dust and contamination levels, offering more coverage and thermal performance compared to traditional cellulose products. Additionally, the product features fire safety, limits smoldering and flame propagation, and provides insulation without the risk of ammonia odors or corrosion issues. 

The company intends to use the October 2024 funding to expand production facilities that convert recycled cardboard boxes into cellulose building insulation.
