After the transformation

2023 2022 2021
  • 2023

    • The first half of 2023 was characterised by great challenges, which not only affected the general economy but the building sector in particular and thus Arbonia.
    • As an expression of its strategy, Arbonia has decided to rename the HVAC Division the "Climate Division". The new division name emphasizes its international orientation and focus on cutting-edge products and energy-efficient systems. The portfolio of the division ranges from sustainable heat/cold generation, the storage of heat and energy, to heat/cold distribution, as well as ventilation and air filtration. The Climate Division supports the future-proof supply of energy and heat to all kinds of buildings and is thus ideally equipped for the energy revolution in the building sector.
  • 2022

    • 2022 is a challenging year due to material price increases, the energy crisis, supply bottlenecks and the strength of the Swiss franc.
    • However, Arbonia continues to focus on the further development of modern products for energy-efficient and self-sufficient buildings, such as heat pumps, ventilation systems, underfloor heating and battery storage.
    • In the doors segment, the new door frame plant in Prüm (D) opened, and the construction of the new logistics centre in Roggwil (CH) will shorten delivery times for customers in Switzerland.

    • The Sanitary Division will be integrated into the Doors Division as the Glass Solutions Business Unit as of 1 July 2021.
    • Arbonia acquires Termovent Komerc d.o.o. (Termovent). The acquisition of the established Serbian manufacturer of commercial ventilation equipment represents the geographical expansion of its holistic system offering in the area of ventilation into Eastern Europe, as well as the expansion of its expertise in the area of indoor air quality, particularly cleanrooms.
    • Arbonia acquires the Spanish market leader in the distribution of designer radiators and bathroom radiators, CICSA Industriales del Calor S.L. (Cicsa). 
    • In January 2021, Arbonia announces the sale of the Windows Division.
