Hemp Houses – The Secret of Building Sustainable Homes

Once the areas major agricultural product, hemp is making a comeback in the Altiplano area of Granada, Spain. Until the late nineteen sixties industrial hemp growing formed the backbone with this wholly agricultural area of Spain. Towards the finish of the Franco era, with the invention of nylon and the mechanisation of agriculture all the population was forced off the land to get focus on the coast and major cities.

With the advent of the eco-age the interest in industrial hemp has been revived because it is really a major constituent of eco-bricks, a vital element of sustainable housing.

Hemp originates from the Anglo Saxon word’haemp’and is the most popular name for plants of the cannabis genus. Hemp usually identifies the strains of the plant cultivated exclusively for industrial use rather than cannabis that will be connected with pot and similar drugs.

Hemp has a huge variety of uses but continues to be overshadowed by the cannabis connotation of illegal drugs, with which it is often confused. However hemp can legally be grown, under licence, in lots of countries, such as the European Union countries and Canada.

Cannabis sativa L. may be the variety primarily grown for industrial purposes, it is really a fast growing plant and has been cultivated for several thousand of years getting used to make rope, clothing, paper, hemp oil and medicines. Growing hemp improves the problem of the floor and reduces ambient contamination. It’s a robust plant that requires neither herbicides nor pesticides during its cultivation.

Hemp as an industrial material has a ten thousand year history. The initial recorded utilization of hemp was as a towel fabric, within China as far back as 8000BC.C. Circa 4000B.C. hemp started to be used, again in China, to make ropes and as food. 2000 years later, the Chinese hemp oils and medicine were in use. By 1000B.C. its use had spread to India and Greece where the first instances of hemp paper were found. how to use kratom

By the 6th century hemp was being utilized in Europe in some amazing ways, in France a hemp reinforced bridge was built and it is still in use today. The hemp fibre also found uses in sailmaking, caulking materials, fishing nets and lines. In later years hemp was used to make many different foodstuffs including butter and beer.

Today industrial hemp can be used to create a staggering variety of products including medicines, body maintenance systems, building and insulating materials, clothing, textiles, food, fuel, livestock food and bedding, plastics and paper.

In the building industry hemp bricks, for their sustainability and excellent insulation properties, are being used to make external and internal walls of ecological homes. In this area of Spain the external walls of an eco house will include a eco-bricks, manufactured in Guadix with the proprietary name of Cannabric® ;.

Cannabric® derives its properties from industrial hemp fibres (cáñamo). The hemp bricks are comprised of industrial hemp fibres, slaked lime and an assortment of innert mineral materials. The bricks combine the functions of lots bearing wall that is fire-resistant and doesn’t require the addition of thermal or acoustic insulation.

The most important element of the eco-brick is industrial hemp that includes a very low thermal conductivity (0.048W/m²k) producing a stone with vastly superior insulation properties against both cold and heat. The mineral element of the bricks gives them their mechanical strength. Being fully a solid brick, with a high specific heat, it has the perfect thermal properties to safeguard against heat.
