The video opens with an on-site narration: what is being installed now is the CBD Jiaming Center project. The person on camera is Guo Rui, founder of Zhongke Energy Consumption Control — better known in the trade as “Lao Guo” or “Guo Daxia”.
The Jiaming Center order came from the tenant side: some tenants reported that window-side areas felt hot on clear days, and the owner, valuing the office experience inside the building, wanted an improvement without touching the curtain wall. The video records the installation: track and film assembled section by section on the inner side of the glass, with Guo Rui confirming key points on site — every step accounted for, from positioning to edge finishing.

The founder showing up to supervise reflects a simple delivery standard: installation quality directly determines the curtain’s final performance — an uneven film or a loose edge will be magnified in everyday use.
For office-building owners, window-side heat is one of the most frequent complaints; for tenants, whether a desk by the window is usable directly affects workstation utilisation. The curtain addresses that strip of window-side space and improves the experience of the whole floor.
Jiaming Center is a case already published on our website. The full installation video is available on the company website and official short-video accounts.
