The verified reports cover TimberBoard, TimberBatt, and TimberFill, documenting the environmental impact of these materials under ISO 21930 and ISO 14025 standards. By utilizing wood residuals from regional forest-products industries, the company integrates biogenic carbon directly into the building envelope. Unlike conventional mineral wool or foam insulation, which typically introduce an embodied carbon burden before a building is occupied, these wood-based alternatives sequester carbon throughout their service life.

TimberHP Secures Negative Carbon Footprint Certification for Insulation
Madison-based manufacturer TimberHP has published independently verified Environmental Product Declarations for its entire wood-fiber insulation line, confirming that its products store more carbon than they emit during production. This cradle-to-gate negative carbon footprint offers architects a new tool to lower the embodied carbon profile of modern building projects.
Beyond sequestration, the insulation system provides high thermal performance and moisture resilience. Because wood fiber is vapor-open, the material supports drying potential within wall assemblies, which can extend the longevity of the structure. CEO Matt O'Malia stated that these EPDs provide the transparency necessary for developers to meet sustainability goals, shifting the focus from simply reducing emissions to immediate carbon storage in construction.
