Currently, the most technologically advanced building walls have an overall heat transfer coefficient U at a level of 0.10 W/(m2K) which corresponds to the passive house standard. Less demanding requirements are set for building windows for which the thermal performance has not yet been significantly improved. Therefore, there is a demand for developing new technologies for glazing with superior thermal performance, good optical quality and of the lowest possible weight. In the paper, measurements of thermal performance of multi-layer glazing with ultrathin internal glass partitions are presented.
