ClimAd Technology is a tech start-up founded in 2019 by Dr. Stijn Kragt and Prof. Guofu Zhou. After a successful PhD project at the Eindhoven University of Technology we decided to develop our knowledge on reflective coatings further for window application. Glass facades are increasingly dominating the appearance, comfort and energy consumption of the urban landscape. Integrating our window films in buildings and vehicles will create a colorful, lively and energy-efficient society. That is why we innovate!
