ECONTROL® – Technology meets aesthetics

The façade is a building's "figurehead". It is an element of marketing and the public representation of the building. It should therefore be aesthetically pleasing.

In modern architecture, the standards are even higher.

Architectural visions combine openness and transparency with aesthetics, technology and energy efficiency.

ECONTROL®, the intelligent façade glazing, unites all these aspects with its innovative technology.

The electrochromic glass contains an internal coating that changes its colour as soon as a small electric current is applied. Through this so-called "electrochromic effect", the glass turns a blue shade and ensures a comfortable climate in the rooms behind it.

The linked PDF file provides detailed information about the ECONTROL® technology.
