In the children’s story, the Three Little Pigs, the straw house gets blown apart by the big, bad wolf. If that piggie had used hemp instead, it would have survived.

Hemp is one of the fastest growing plants, a non-psychoactive form of marijuana/cannabis, which can be part of the walls (hempcrete) and insulation (HempWool.)

HempWool insulation is made from 90% hemp fibers and 10% binder. It is the only insulation on the market that is carbon negative. This means that architects can lower a building’s embodied carbon footprint by integrating HempWool for a project’s insulation needs. Additionally, the panels are safe to be handled without gloves and can be used for floors, walls and ceilings to provide acoustic and thermal insulation.
