Hemp Insulation

Product Description

Thermo-Hemp is a natural insulation material manufactured from hemp by THERMO NATUR in Bavaria, Germany.  Hemp grows up to a height of nearly 4 metres within a period of 100-120 days. Because the plants shade the soil, no chemical protection or toxic additives are required for hemp cultivation. As well as having low embodied energy during manufacture, hemp is carbon negative as it locks in carbon during its growth.
