Straw is the ideal insulation material: It grows as a by-product on the field, and is left as waste after the harvest. Straw can be processed to make an insulation without altering it´s natural shape. ISO-straw is untreated and has natural properties decreasing it´s flammability. ISO-straw is the most ecological way to insulate, and the most natural way to live.
