Additionally, it is capable of assisting in regulating the humidity of the environment, keeping the air around the walls cool and subtly humid. Given this characteristic and its good thermal inertia, it improves thermal comfort in both heat and cold, in both drought and rain.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Energy efficiency \u2014 The characteristics described above and the breathability of the material allow for building spaces that do not require heating in winter and cooling in summer, saving energy.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Acoustic comfort \u2014 Hemp shives are good acoustic insulators. Even a thin panel, which is very light, greatly reduces the discomfort caused by noise. In tests, sound absorption varied between 0.24 and 0.53, depending on the frequency.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Mechanical properties \u2014 Although hempcrete is not suitable for structuring a tall construction, its characteristics make it a resistant material, capable of having great durability in difficult situations. It is not rigid \u2014 it can accommodate movements, which is useful in regions where there are seismic shocks. Even so, it does not bend: its resistance to flexion is equivalent to blocks of gypsum or concrete.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Lightness \u2014 Very light and resistant, Hemp shives result in a material that is easy to handle and practical to use.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Multiple resistances \u2014 The material showed excellent performance in resistance to fires and termites.<\/span><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Versatility \u2014 The fact that it can be sprayed or molded on-site opens up multiple opportunities to invent new ways to use Hemp.<\/span><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Contraindications \u2014 Hempcrete is not recommended in freezing areas \u2014 the cycle of freezing and thawing can compromise its durability. It is also not recommended to use it excessively exposed to moisture. Although it is self-supporting for constructions of up to two floors, it is not indicated for structural use beyond that.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\"><strong>Source:<\/strong> <em>Ansari H, Tabish M, Zaheer M. \u201c<a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2949823624000527#sec0035\">A comprehensive review on the properties of hemp incorporated concrete: An approach to low carbon footprint construction<\/a>\u201d. 2025.<\/em><\/span><\/p>\n\t<\/div>\n<\/div>\n\n\n\n<div class=\"img-with-aniamtion-wrap center\" data-max-width=\"100%\" data-max-width-mobile=\"default\" data-shadow=\"none\" data-animation=\"none\" >\n      <div class=\"inner\">\n        <div class=\"hover-wrap\"> \n          <div class=\"hover-wrap-inner\">\n            <a href=\"https:\/\/hemp.humanitas360.org\/wp-content\/uploads\/2025\/04\/matoHemp.webp\" aria-label=\"Pedestalled dish from the Jomon people in Japan (10,500-300 BCE), one of the most vibrant ceramic traditions in history.
