Hemp can be processed into materials for construction with special thermal, acoustic and bio-climatic qualities.
Fibers from the hemp stalk are mixed with natural binding agents to form a composite that is biodegradable and recyclable. It is recommended for architects and owners aiming to build environmentally responsible buildings and create more comfortable and healthier spaces of high quality and durability.
Hempcrete is a mixture of hemp fibers and lime, possibly including sand and cement. It can be used for construction and insulation. It is easier to work with than traditional lime mixes and acts as a temperature and moisture regulator. It is not brittle like cement and consequently does not need expansion joints.
The density of the bricks is 15% that of traditional concrete. The manufacture of the bricks is carbon negative. Their strength and flexibility means that hemp foundations are resistant to stress-induced cracking and breaking. This eco-brick si self-insulating, resistant to mold, rodents and insects, fireproof and waterproof.
Hemp hurds are extracted from the inner core of the plant stem. The processed material is highly absorbent, rich in cellulose and possesses great thermal and acoustic properties. It can be used for woodless, sustainable animal bedding, and as an alternative green building material for such applications as hemp concrete, biodegradable garden mulch, lightweight board, acoustical ceiling and wall tiles, non-wood plastic filler and other innovative eco-friendly bio-products.
– Excellent thermal insulation, a porous material that traps air, leading to a low thermal conductivity – Excellent acoustic insulation – Excellent humidity regulation, without loss of the insulating qualities. – Easy to shape for use in irregular spaces. – Hypoallergenic, recyclable, good mechanical resistance. – Durable, since hemp is a natural fiber that does not contain albumen, there is no risk of infestation from pests, fungus or mold.
