- Note: Wicona is one of the Hydro Building Systems brands, alongside Technal, Domal and the former Sapa Building System – this whole package belongs to Norsk Hydro, which makes the group the largest integrated supplier of architectural aluminium in Europe. In these systems Hydro offers Hydro CIRCAL profiles with a guaranteed content of at least 75 percent post-consumer scrap and Hydro REDUXA with a reduced carbon footprint of primary metal. This is the most far-reaching declaration of secondary material content in the entire construction segment – and the only one based on external verification of scrap origin. Wicona also carries out projects to recover profiles from façade demolition and remelt them into new systems.
