These hempcrete blocks are a green building material made with a hemp-lime insulation mixture packed around a biocomposite structural frame.
You can stack the blocks like bricks to build walls up to 30 feet high, and they become the insulation and the structure of the building. After the walls are built, all you need to do is plaster the inside and outside, and then add windows, doors, and a roof!
The hemp plant sequesters carbon during its growth, and lime, as it dries, reabsorbs the carbon released when it was manufactured, which means the hemp-lime mixture is carbon negative (it sequesters more carbon than carbon it creates in its life cycle). Terry Radford from Just BioFiber says that these hempcrete blocks will sequester about 10 tons of carbon per house.
Not only is this an environmentally friendly building material, it also creates a comfortable living space. The hempcrete helps regulate the temperature and humidity, reducing noise transmission through the walls. It’s also fire-resistant and non-toxic.
This is an incredible green building technology, and we can’t wait to see Just BioFiber ramp up their block production so that we can start to see hempcrete buildings popping up all over the world.
