Hygrothermal properties of advanced bio-based insulation materials

• Hygrothermal material properties of bio-based insulators were determined. Bio-based materials provide high thermal resistance and water vapour permeability. Properties insulations are comparable with conventional materials. performance buildings is one key element to the sustainable design, health, comfort indoor environment. Building sustainability depends on all associated lifespan stages, from building design production demounting waste management. Many unsustainable in terms their environmental impacts. One approach reduce impacts development application The aim this study was determine hygrothermal that promote energy efficiency contribute decreasing buildings. Here, eight new peat-, recycled paper-, wood shaving-, feather-based insulation assessed. Measurements these will improve understanding efficiency, permeability, buildings, retrofits, or both. Data necessary parameters develop a dynamic numerical model. studied appear sufficient performance, which minimum embodied energy.
