Abstract: Unit curtain wall is a common form of curtain wall installation through the application of ad.vanced construction technology and energy-saving technology. Although the design and manufacturingcost of the unit curtain wall is relatively higher, the construction is simple and has a good environmentaprotection effect, so the application range is relatively wide. Combined with the specific project over-view, this paper explores the basic process and specific construction technology of curtain wall installa-tion of large unit plate in commercial buildings, in order to provide some technical references for the cur-tain wall installation of large unit plate in commercial buildings.
