The modern Harol Coolscreen Collection is a sustainable collection of vertical sunshades with a single set of components. The minimalist shape of the box, thanks to screwless guide rails and a hidden base strip, offers planners a wide range of possible applications. Light accents are set by the integrated, dimmable LED lighting, which also increases the security of the building. It is controlled via a remote control, an app or an existing smart home system. The jury was impressed by the reduced design, the attractive lighting option and the well-thought-out integration of the solution. The system is also available in a solar-powered version.
