The certification of buildings according to sustainability criteria is gaining in importance worldwide. Different certification systems, such as DGNB or LEED, use verified product data from product-specific declarations or from general databases for this to calculate the life cycle assessment of buildings. We focus on transparency and real data and therefore have environmental product declarations in accordance with ISO 14025 Type III and EN 15804 for our RHEINZINK-CLASSIC and RHEINZINK-prePATINA product lines.

RHEINZINK has been certified according to the "Cradle to Cradle" criteria since 2009. "Cradle to Cradle" is founded on the philosophy that all materials, including their residual materials, can be converted back into a new product without any loss of quality and thus includes the life cycle consideration from material extraction to renewed use. As opposed to the meaning of recycling, the basis of "Cradle to Cradle" is that a material recovers its original values and is used for a new product of at least equal value (upcycling) and is not used in another, inferior way (downcycling) or can even just be landfilled.

This technical and biological cycle avoids waste and a burden on the environment.

All RHEINZINK roof and façade products, including the complete roof drainage system from the RHEINZINK-CLASSIC and RHEINZINK-prePATINA product lines, are covered by the "Cradle to Cradle" certification. Every two years, the classification status is reviewed and re-evaluated by EPEA.

RHEINZINK's ecological commitment has been evaluated and certified by numerous independent institutes. We document our environmentally responsible actions, for example, by introducing the DIN ISO 14001 environmental management system, tested and certified by TÜV Rheinland, and also by introducing a certified energy management system in accordance with DIN EN ISO 50001. Our aim is to save energy, preserve resources and keep the environmental impact of our products as low as possible.

The shielding properties of RHEINZINK have been determined by the International Society for Electrosmog Research (IGEF e.V.). The measurements to determine the shielding effectiveness against electromagnetic waves in the frequency range of 10 MHz to 4 GHz revealed that the roofs and façades manufactured by RHEINZINK GmbH & Co. KG. attenuate high-frequency radiation from the outside by more than 105 dB. This means a reduction of 99.99999999%. A mere 0.00000001% of the externally incident power could be detected immediately behind the material. Exposure to high-frequency electromagnetic radiation leads, among other things, to insufficient sleep quality, loss of vitality, headaches, tinnitus, lack of concentration, reduced mental and physical resilience as well as increased stress on the cardiovascular system.

RHEINZINK products are not subject to registration in the sense of the REACH regulation, as they are products and not substances. Therefore, only the ingredients as such are to be registered by the manufacturers. Our raw material suppliers have already registered the substances subject to the REACH Regulation.

RHEINZINK products do not contain SVHC substances in concentrations > 0.1% and are therefore not subject to notification.
