Abstract

Transparent insulation materials are a new class of materials, which need new measurement techniques for their correct characterization. These measurement methods are summarized. Besides the data of some newly developed materials, a survey of the most important available materials is given. In addition, the potential of granular aerogel windows is shown. All these data are compared with the state of the art of conventional glazed window units including vacuum windows, which might be possible in the future. The importance of the ratio between the total energy transmittance and the U-value of a window under different climatic conditions is discussed, as a possibility to rate a window.
