How Can Hemp Help?
Did you know that Industrial hemp provides one of the world’s most versatile and sustainable building materials? Hemp hurd, which is the woody core from the centre of the stalk of the plant is a modern solution to other toxic materials that are used in the building world today. This woody core is chipped and mixed with water, lime and a binder to create a high performing alternative to concrete, also known as hempcrete. The hemp core has a high silica content which allows it to bind well with lime. Hempcrete creates beautiful, stone like walls that are warm, modern, affordable and stylish.
Hempcrete has been used in house building for hundreds of years. It was first discovered in France as far back as the 6th century.
Benefits of building with Hempcrete
- Insulation: Hempcrete provides excellent thermal properties, when compared to other types of building materials.
- Constant temperature: Whether you live in cool or warm climates, hempcrete maintains a constant temperature, due to the insulating properties as well as thermal mass, which is excellent for all climates, especially in very hot and cold areas.
- No dampness in walls: Since hempcrete is breathable, you don’t have to worry about damp. Both the hempcrete and the lime plaster work to absorb moisture in the air especially during high humidity, as moisture is released back into the air when humidity levels drop. As a result, mold growth is a thing of the past because hempcrete keeps humidity at levels that prevent bacterial growth.
- Non-toxic: There is no need for fungicides or pesticides to grow hemp, compared with the production of conventional construction materials, which involve toxic and synthetic chemicals.
- Fire retardant: Houses built with hempcrete char a little when they’re burnt, but they’re known to be more fire resistant.
Using hemp in the daily diet and in our homes can make a significant impact on our health and the health of our environment.
