Nanogel windows

Abstract

This chapter deals with the application of highly energy-efficient windows and skylights with silica nanogel as a strategy in the building refurbishment. Aerogel windows seem to have the largest potential for improving the thermal performance and daylight in fenestration industry, because of very low conductivity, density, and a good optical transparency. A state-of-the-art review of nanogel windows in building applications is firstly presented. Then, the proprieties of nanogel glazings in terms of thermal, lighting, and acoustic insulation solutions are discussed. Finally, the potential of the nanogel windows for energy saving in order to achieve a nearly zero-energy building is described, thanks to the results of a case study.
