Statistical analysis of hygrothermal properties of bio-based insulations

---

Abstract

Bio based insulation materials are championed for their low embodied carbon and high moisture buffering capacity. Yet practitioners lack quantitative guidance on how these materials behave under the diverse hygrothermal conditions that characterize different climates. This study collected the hygrothermal material property data for 16 commercially available bio-based insulations, and categorized them into three groups. It was found that the group that has higher density is more likely to have lower heat and moisture capacity, while higher vapor resistance factor and lower water absorption coefficient. The hygrothermal property data provided some insights on how to choose proper materials, while in the future work, hygrothermal simulations will be performed under different climate conditions to investigate the performance of the walls with different insulations.
