Exterior wall construction for buildings, especially a panel in a building wall's chest area

摘要

Here is a new external wall structure for buildings. It takes the form of outer panelling, designed to make use of solar energy. To this end it has a partially-transparent external layer (1) and an inner layer (3) including thermal insulation (2). The external layer (4) is plain-, multilayer- or laminated glass, or their combinations. On the inner surface of the glass, visible externally, there is a functional layer (5). The novel feature is partial transparency of this layer to solar radiation; however, it appears opaque to the eye. It comprises insular dots of regular or irregular shape, distributed over the glass surface. These are opaque. The tiny spacing between individual adjacent dots is limited to a maximum set value. These gaps are so small in themselves, that close observation by the human eye is unable to resolve them.
