Abstract
An outer wall element for buildings wherein, between the inner wall shell and a solar-radiation permeable outer wall shell, a solar-radiation permeable and heat-insulating layer is arranged, the latter being separated from an inner heat-insulating layer of the inner wall shell by an interface that absorbs the solar radiation from the outer heat-insulating layer. At least the inner wall shell is provided with marginal lining elements, which can be parts of a frame, panels or the like, extending at least up to the interface and conveying heat to the inner wall side. In order to protect the lining elements from the high temperatures reached in the outer heat-insulating layer because of the use of solar energy, the outer heat-insulating layer and the lining elements are separated from each other by insulating elements with poor heat conductivity, which starting from the lining elements cover the inner heat-insulating layer along a marginal strip in the interface.
