MADISON, Maine — TimberHP, the first U.S.-based manufacturer of wood fiber insulation, announced a strategic investment from FTAI Infrastructure Inc., 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.

Matthew O’Malia, CEO of TimberHP, said: “Since founding TimberHP in 2017, our vision has been to bring cost-competitive, carbon-negative insulation products to the North American mass market. This partnership with FTAI Infrastructure marks a pivotal moment for our company, enabling us to accelerate our growth and scale production to meet the rising demand for bio-based building materials to replace energy-intensive non-renewable insulation products that dominate the market. We’re happy to have FTAI join our group of equity investors alongside financing partners BlackRock, the Finance Authority of Maine, and other municipal bond investors that have been highly supportive of our company. We believe this is the beginning of a broader transformation in how buildings are built, and we are proud to play a leading role in shaping a more sustainable future for the built environment.”
