Hemp Applications #1

One of the most common uses of hemp fibers are the coating of thermal insulation for buildings.


According to Quercus to build a sustainable and appropriate energy efficiency of buildings reduces 40% to 50% of CO ₂ and up to 40% of national energy consumption .

In Portugal, when insulation systems are used, products made from extruded polystyrene are the most common choice. These materials are very little environmentally "friendly".


The green roofs made of hemp fibers are one of the best thermal and acoustic insulation systems on the market, with a heat capacity of about 1700 calories J / Kg.K and a thermal conductivity of around 0040 W / mK (the extruded polystyrene rounds 0036 W / mK).


The market price is around 5.6 euros per square meter, cheaper than some types of coverage of polystyrene. For each kg of hemp coverage applied 1.4 kg of CO2 is recovered.

The following is a list of some producers of Hemp roofing insulators :
