The essence of this renovation is that the precise arc craftsmanship shapes the modern aesthetics and humanized experience of the space, while the nested layers of high-performance thermal insulation and sound insulation materials are like invisible guardians, building a second or even third environmental barrier after the curtain wall system. The tenant office finally presented not only has a pleasant and smooth visual and spatial sense, but also a high-quality workplace with a constant temperature (warm in winter and cool in summer), quiet and pleasant, and significantly reduced energy consumption. It perfectly fits the positioning of the Jinmao Twin Towers as a top green and intelligent building, and also provides excellent employee welfare and sustainable operation foundation for the companies settled in.
