HempFlax Building Solutions

Europe's largest producer of industrial hemp manufactures Thermo Hanf insulation from seed to panel.

HempFlax Building Solutions

Description

The largest independent grower and processor of industrial hemp in Europe, based in Oude Pekela (Netherlands) with its own fields since 1994. After acquiring the German company Thermo Natur, it manufactures and sells hemp fibre insulation such as Thermo Hanf, as well as hemp shiv for lime-hemp lightweight concretes. It controls the whole chain, from seed to product, giving it full traceability over a crop that needs hardly any plant protection products and captures CO2 quickly. It supplies the whole of Europe from its Dutch and German plants.

Why we chose it

Because it controls hemp from seed to insulation panel, something almost no one else in Europe can claim.
