Rauta Group has announced that sandwich panels with Cor-Ten steel cladding can combine striking architectural aesthetics with improved energy efficiency in buildings.
As noted in the company’s press release dated March 1, 2026, in 2021, Finland’s Ruukki introduced Patina sandwich panels with mineral wool filling, where the outer cladding is made of Cor-Ten and the inner cladding is made of polymer-coated steel. It also points to the patented shape of the locks, which is designed to prevent internal corrosion at the joints.
Rauta Group emphasizes that Cor-Ten forms a protective patina and does not require painting, and the service life of Patina sandwich panels is estimated at more than 50 years.
In its examples of use, the company also claims that it is possible to save up to 30% on heating and air conditioning costs thanks to the airtightness of the panels and the increase in the energy class of the building, as well as compliance with environmental criteria, which can be taken into account during LEED and BREEAM certification.
Rauta is a leader in the Ukrainian steel construction market and a member of the European Construction Industry Association. The company provides design, manufacturing, and installation solutions in accordance with current EU standards. The company is licensed to perform construction work with medium and significant consequences (CC2, CC3).
