The chapter deals with the potential of highly energy efficient windows with silica aerogel for energy saving in buildings. Aerogel is a low density nanostructured porous material with very low thermal conductivity (about 0.018 W/m K for translucent granular aerogel at room temperature) and excellent acoustic insulation. It is ideal for energy saving in buildings, also due to its good optical transparency. The characteristics of the raw material (silica aerogel for windows: monolithic and translucent granular) are illustrated with general information about the production process, the main chemical and physical properties, and a market overview; then, nanogel windows are discussed and thermal, visual, and acoustic performance are highlighted. A useful worldwide market overview about the commercial products and the main manufactures is also included. Finally, a state of the art review of nanogel windows in building applications is discussed: the potential of the investigated solutions is described by both experimental results and simulation models of the aerogel windows performance, referring to different case studies. Future research, market trends, and costs are also discussed.

Abstract
The chapter deals with the potential of highly energy efficient windows with silica aerogel for energy saving in buildings. Aerogel is a low density nanostructured porous material with very low thermal conductivity (about 0.018 W/m K for translucent granular aerogel at room temperature) and excellent acoustic insulation. It is ideal for energy saving in buildings, also due to its good optical transparency. The characteristics of the raw material (silica aerogel for windows: monolithic and translucent granular) are illustrated with general information about the production process, the main chemical and physical properties, and a market overview; then, nanogel windows are discussed and thermal, visual, and acoustic performance are highlighted. A useful worldwide market overview about the commercial products and the main manufactures is also included. Finally, a state of the art review of nanogel windows in building applications is discussed: the potential of the investigated solutions is described by both experimental results and simulation models of the aerogel windows performance, referring to different case studies. Future research, market trends, and costs are also discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
