Wood Preservation

Wood in contact with the ground or exposed to the weather needs special active ingredients and impregnation processes to ensure lasting protection against wood-destroying fungi and insects. This is accomplished through chemical wood protection.


Copper compounds have played a central role for many decades. They represent important biocides in wood protection products for industrial usage. The properties of copper containing wood preservatives are unique because they combine fungicidal, insecticidal and bactericidal properties with a broad efficacy.


The Biocidal Product Regulations 528/2012 (EU BPR) is applied as the basis for the usage of wood preservative products.


This guideline as part of the European chemical act prescribes a registration of active ingredients with an official registration authority. Spiess-Urania Chemicals GmbH ensures the compliant procedure with its own registration department and corresponding investments.


Spiess-Urania Chemicals GmbH produces the active substances Basic Copper Carbonate and Copper Hydroxide in the company’s salt production facility in Hamburg.
