Aerogel Energy-saving renovation of the exterior facade of Shanghai Book City

The internal insulation of the exterior walls uses 2cm thick aerogel inorganic insulation paste The eave part of the second floor floor is designed to be coated with 2mm aerogel thermal insulation paint The aerogel exterior wall internal insulation system has excellent heat insulation and heat preservation performance, good hydrophobicity and moisture-proof performance, and is applied by scraping. The original exterior walls of the building envelope of Shanghai Book City were thick concrete walls without any insulation materials. After the renovation, 2 cm thick aerogel inorganic insulation paste was used for the internal insulation of the exterior walls. The eave part of the second floor floor was designed to be coated with 2 mm thick aerogel thermal insulation paint. The carbon emission factor of the aerogel material is only 1/2 to 1/3 of that of rock wool board, meeting the latest national standard requirements at the same time Try to minimize the thickness of the insulation layer.
