Climate Glass

High Tech for Highest Demands

Current global subjects do matter us as well. Therefore, PR Germany focuses on environmental protection. This plays a significant role particularly regarding the installation of glass in modern architecture.

Since people have a clear preference towards light-flooded rooms, the installation of preferably big window areas gain increasing popularity. Considering the isolation or the possible energy loss of a house, windows and doors form the weakest link in the chain.

Efficiency. Aesthetics. Environmental protection.

For a long time, our company has been dealing with the question on how to increase the energy efficiency of a building and in this regards with the chances for actively and controlled regulation of temperatures through glass surface.

The problem solving approach results from the natural example of a cave. On closer inspection it becomes clear that even in hot desert regions the temperatures inside are significantly lower in the cave than in the environment – even without a direct air draft. The room temperature is regulated by the surrounding cold rocks. How can we use this principle?

The PR Climate Window

In combination with its special frame, the PR Climate window is an extraordinary system. The cooling and heating elements integrated in the frame allow to cool or heat the glass panels filled with specific gas.

The necessary energy is won by the photovoltaic cells that are integrated in glass and frame and regulated by an electronic control unit. During the first tests, prototypes achieved a difference in temperature of +/- 12°C. Thus, this system is able to relieve both air conditioners and heating systems and improve the energy efficiency of the building.

The PR Climate window already sets new standards in the building technology due to the combination of innovative, environmentally friendly technologies and the model of nature. We are continuously improving this product through ongoing research and further development. Not only hot regions are possible application areas, but also all architectonical planning that incorporate the installation of glass surfaces.
