Recently, Central South University has successfully developed a "new transparent aerogel material", which is the lightest solid material known in the world and the best thermal insulation material to date. The appraisal committee composed of experts from the Ministry of Housing and Urban-Rural Development, China Academy of Building Research, Tsinghua University, Central South University and other units believes that the technology is at the international advanced level and already has the conditions for industrialization.
The "Research on New Transparent Aerogel Materials and Their Application in Building Energy Conservation" project completed by Central South University has developed a new sol-gel orientation control technology, which not only improves the strength of the gel, but also ensures the gas For the transparency of the gel, we have taken the lead in developing large-scale and complete transparent aerogel large-scale processes at home and abroad, forming a complete set of transparent aerogel preparation technology and equipment, which can realize large-scale production and reduce costs by more than 50%. The new type of transparent aerogel energy-saving glass developed by the project team has ultra-low heat transfer coefficient and good light transmittance, which can meet the needs of higher energy-saving indexes of buildings and more advanced green buildings.

The new type of transparent aerogel energy-saving glass developed by the project team has ultra-low heat transfer coefficient and good light transmittance, which can meet the needs of higher energy-saving indexes of buildings and more advanced green buildings.
It is understood that the external doors and windows in the building are the weakest parts of the thermal insulation in the envelope structure, and the energy consumption lost through it has exceeded 50% of the total energy consumption of the building envelope structure. Experts believe that the market potential of the new transparent aerogel is huge, and the promotion and application of this achievement will greatly improve China's building energy efficiency and promote energy conservation and emission reduction in the field of urban and rural construction.
