Everyday heroes

Our work is not just about technical details but about creating an invisible but indispensable solution that makes everyday life smooth for all of us. Our work goes beyond just being technical experts, installers and fitters - it's about being part of every person's everyday life and making it comfortable and sustainable.

Without our work, online work would have suffered as server halls would have overheated, no milk carton would have been on the breakfast table if the paper mills were not properly insulated, and the swimming pools where we take our children on weekends would have been closed if the right climate was not ensured by insulation.

Thermion doesn't just insulate processes and factories; we insulate and improve people's lives.

Environmental benefits

Technical insulation and energy efficiency measures reduce both heat loss and energy consumption. This results in significant cost savings and a greener world. The average annual impact of Thermion projects can be compared to energy savings of almost 2,000,000 kWh. 

This is roughly equivalent to the CO2 emissions of
The incineration of 4300 tonnes of waste (generated by 430 people in 10 years),
200 years of solar electricity production for an average household, or
Driving an average car 399 laps around the globe
