Academic Findings on Thermal Performance
Researchers at the University of Bologna published peer-reviewed results on July 2, 2026, examining the thermal conductivity of hemp-fiber insulation panels under Mediterranean climate conditions. The two-year field study compared panels made from Italian-grown hemp against mineral wool and recycled polyester controls.
Key Results
Hemp panels demonstrated thermal conductivity values within 5 percent of mineral wool while offering improved moisture buffering. The study also recorded lower embodied energy during manufacturing when local hemp feedstock was used.
Industry Relevance
Construction material suppliers have expressed interest in the findings as European building codes increasingly favor bio-based insulation. The research team emphasized that results are specific to the tested density and binder formulations and recommended further long-term durability testing.
The paper is available in the July issue of the Journal of Building Engineering.
