referenceHempcrete-microencapsulated phase change material composites have been analyzed for their thermal, microstructural, and numerical properties in a 2020 study published in Applied Thermal Engineering.
claimHemp fibers used in construction materials like hempcrete, insulation, or biocomposites provide long-term carbon storage, according to Collet and Pretot (2014).
claimAmong previous Life Cycle Assessment (LCA) studies on hemp, building materials, hempcrete, and insulation were the most frequently studied products.
claimHempcrete is used in floor, roof, and wall insulation due to its thermal insulation, breathability, fire-resistance, and acoustic properties, which help regulate indoor temperature and reduce the need for active heating or cooling.
