Hemp Houses – The Secret of Building Sustainable Homes

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

With the advent of the eco-age the curiosity about industrial hemp will be revived because it is a major constituent of eco-bricks, an essential element of sustainable housing.

Hemp arises from the Anglo Saxon word’haemp’and is the favorite term for plants of the cannabis genus. Hemp usually identifies the strains of the plant cultivated just for industrial use in place of cannabis that will be associated with pot and similar drugs.

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

Cannabis sativa L. is the variety primarily grown for industrial purposes, it is a fast growing plant and has been cultivated for many thousand of years getting used to make rope, clothing, paper, hemp oil and medicines. Growing hemp improves the situation of the bottom and reduces ambient contamination. It is a strong plant that requires neither herbicides nor pesticides during its cultivation.

Hemp as a professional material includes a ten thousand year history. The initial recorded use of hemp was as a towel fabric, within China as far back as 8000BC.C. Circa 4000B.C. hemp grew to become 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 very first instances of hemp paper were found.

By the 6th century hemp was being found in Europe in certain 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 a variety of foodstuffs including butter and beer. By the 15th century Renaissance painters were utilizing hemp canvases. best kratom for energy

Today industrial hemp can be used to create a staggering number of products which range from 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, because of their sustainability and excellent insulation properties, are increasingly being used to create 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 a lot 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 suprisingly 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 a solid brick, with a high specific heat, it’s the suitable thermal properties to guard against heat.
