The Tiangu Yasha Residential Project is the first passive ultra-low energy consumption building in Xi'an. Compared with traditional buildings, the comprehensive energy-saving rate of passive ultra-low-energy consumption buildings is more than 90%. By relying only on the structural design of the building itself, it is possible to achieve the constant temperature, humidity, oxygen, static and clean effect that can only be achieved by electrical appliances. Our company mainly participates in the supply of airtight membrane materials and specialized MS adhesive materials.
