Every time we publish an article about Hempcrete, we get a lot of comments on social media - with a certain level of irony - about what would happen if the material caught fire. This is actually a legitimate question, as there is still a lot of confusion about the differences between marijuana and hemp, both of which come from the same plant species (Cannabis Sativa). But while marijuana has psychoactive effects due to tetrahydrocannabinol (THC), mainly present in the flowers of the plant, hemp-based building materials are produced from its stem, which contains small amounts of THC. To quickly answer the title question: no, the building won't be destroyed in the event of a fire. In fact, some tests have shown that these materials have excellent behavior against fire, dissipate flames, maintain structural integrity, and don't emit toxic smoke.
Hempcrete: The Latest Architecture and News
Hemp is one of the oldest crops domesticated by humans. With its wide variety of uses and applications, it’s easy to understand why it’s been a desirable product throughout history. Hemp seeds and flowers are used in health foods, medicines, and organic beauty products; the fibers and stalks of the hemp plant are used in clothing, paper, and biofuel. Today even a waste product of hemp fiber processing, so-called hemp shives, is being utilized to create sustainable building materials like hempcrete.
