As per estimates by the U.S. Green Building Council, buildings account for thirty-eight percent of the CO2 emissions in the U.S.
Considering the requirement of carbon neutral building material, U.K.-based Lhoist Group has created Hemcrete®, a bio-composite, thermal walling material made from hemp, lime, and water.
Recently, construction of America’s first hemp house was completed by Builder Gary Rogers. Loaded with a number of eco-friendly features, this house is constructed in Asheville, North Carolina.
The hemp walls are not only good looking but have many other properties too. They are termite resistant, fireproof, breathable, 100% recyclable, prevent mold, store carbon, and insulate well.
Rogers said, “The hemp is basically encased around your timber frame home so in a nutshell it’s your cladding, it’s your insulation, and it’s all your gyprock and basically all your painting, all done in one, in a monolithic wall.”
Hempcrete is non–structural and is more like infill straw bale. The insulating quality of Hempcrete is r-2.5 per inch. It can capture airborne pollutants and it absorbs carbon. This amazing material has a high thermal mass that helps in maintaining a steady interior temperature as well.
The hemp house gives the privilege to live in a place that is not only safe and non-toxic but also helps in cleaning the air, the earth, and our bodies.
