The Vital-Energy-Window creates an atmosphere to feel well! An innovative new development: The Vital-Energy-Window uses sun energy in winter. Similar to a tiled stove it stores and releases it into the room. Even diffused light is enough to heat the room noticeably. At night the window prevents the existing heat from dispersing to the outside. In summer the absorptiondisc can be turned and thus used as a strong sunshade without additional shading.
