TimberHP, the first U.S.-based manufacturer of wood fiber insulation, announced a strategic investment from FTAI Infrastructure Inc. (NASDAQ: FIP), managed by Fortress Investment Group. The investment marks a significant milestone in TimberHP’s growth and will support the continued ramp-up of production at its Madison, Maine facility and the expansion of its commercial footprint across North America. 

As demand increases for cost-effective, low-carbon building materials, the partnership positions TimberHP to better scale safer, more sustainable insulation solutions while boosting U.S. manufacturing. The collaboration reflects a shared commitment to advancing high-performance building materials and accelerating the transition to more sustainable construction practices. By utilizing abundant residual softwood chips, a by-product of logging and lumber production, wood fiber insulation supports responsible forest management.
