Current market environment leads to lower sales at Zehnder Group
  • Zehnder Group sales fell by 7% to EUR 705.8 million in 2024. Geopolitical and economic uncertainty as well as high construction costs led to a decline in construction and renovation activities
  • Sales in the ventilation segment decreased by 4% to EUR 424.2 million, influenced by the decrease in new residential construction. The Siber acquisition contributed positively, adding 4% to ventilation sales
  • In the radiator segment, sales fell by 12% to EUR 281.6 million, primarily due to the decline in renovation activities
