of modern production and office complex area, which includes production halls for PVC, aluminum, and wooden fenestration, an Insulated Glass Unit Production Plant, and a Training and Exhibition Center, which supports our sales, marketing, and training activities.
We are constantly developing technologies that set the direction for the growth of our company and the entire industry. At the Research and Development Center, we have developed, among other things, our proprietary SUPERtermo glass technology, which allows us to achieve a heat transfer coefficient Ug = 0.5 W/m²K – one of the best results in its class. Full quality control is ensured by our own Insulated Glass Unit Production Plant, where our glazing units are manufactured. We continuously invest in expanding our modern machine park to better respond to current market needs.
We cooperate with the most important industry research and development units. These include: the Building Research Institute, the Institute of Ceramics and Building Materials, the Polish Passive House Institute, the Lower Silesian Energy Agency, the Polish Windows and Doors Association, the Metalplast Złotów Measurement and Research Laboratory, as well as the University of Trondheim and the Institute for Fenestration Research in Rosenheim.
