Jordan Nature-Pur, the pure mineral, biocide- and solvent-free wood preservative stain for interior and exterior wood from Jordan Lacke, has successfully passed the QNG-ready certification of the Sentinel Haus Institut. The Sentinel Haus Institute tests building products for health quality in accordance with QNG Annex Document 3.1.3.
The wood preservative glaze thus contributes to building owners receiving a subsidy from the Kreditanstalt für Wiederaufbau KfW (KfW Reconstruction Loan Corporation) for their new building. This is because this subsidy is linked to certain sustainability criteria, which are confirmed by the state quality seal Sustainable Buildings (QNG). This official government seal of quality looks at the building and its surroundings as a system; the entire life cycle, including production and subsequent recycling of materials, as well as the impact on health, play a role here.
