Abstract
Transparent or translucent insulation materials (TIMs) represent a new class of materials with a high potential for increasing the efficiency of solar thermal conversion systems. A large number of materials have been subjected to theoretical and experimental investigation. If all materials that suppress heat losses but are transparent to solar radiation, vacuum, certain gases, convection barriers, etc, can be regarded as TIMs. Exploratory field and laboratory studies of degraded FEP-film convection barriers in flat plane thermal solar collectors are described. The study related to collectors that had been operating in Sweden for periods of one year to ten years. Both physical, functional (thermal) and chemical aspects of degradation were considered. The report identifies the mistakes made so that they need not be repeated by the solar collector manufacturers in the future. 11 refs, 59 figs, 11 tabs
