The building envelop with different material types, different types of waterproof and power saving structural measures for external wall, and whole-precasting bathroom modules and kitchen modules were finally assembled to reach good insulation, energy efficiency and waterproof effects.
This method can fulfill the earthquake resistance requirement and the construction technology of this method is simple, reliable, good in quality, and no special in material requirement.
