Application of fluids and promising materials as advanced inter-pane media in multi-glazing windows for thermal and energy performance improvement: A review

Multi-glazing (including double-glazing) windows have attracted increasing attention in recent years due to their effective performance saving energy consumption. The common medium between two glass panes is stationary air or inert gas and it could be treated as an extra component multi-glazing windows. This opens possibilities apply different fluids promising filling materials, including airflows, flowing liquids, aerogels phase change materials (PCMs), advanced inter-pane media further enhance window match requirements climates. To facilitate the application development of such technologies, this paper aims provide a comprehensive review mainly including: assessment methods indicators, analysis technologies. Also, comparison potentials mediums climates provided. In addition, suggestions for future works are given based on current progress.
