Aero gel is a solid with the lowest known density. It stands up to 2000 time’s greater load than its own weight. It has extremely low thermal conductivity; the material is very suitable to limit the heat losses of buildings. Its melting temperature is 1200 °C. Well dampens vibration and sound. Aero gel is the only compound with significant thermal insulation capabilities, which is currently well clear. Thanks to these properties have fifteen records in the Guinness Book of Records. For these reasons, it is possible to consider aero gel as a material of the future not only in construction, and therefore it is necessary to deal with this interesting material now. The future use of aerogels as filler in thermall insulating glazing will cause a significant reduction of heat transfer coefficient in lightweight claddings, this follows from the results of our calculations. The bluish color of aerogels is not always a bad thing.
