The two questions most often asked about the curtain are: “Can you still see out after it is lowered?” and “Can you see in from outside?” This video demonstrates both at an installation site in one go.
The demonstration is given by Manager Guo of Zhongke Energy Consumption Control. He stands at the window and the camera follows the curtain: looking out from inside during the day, buildings, trees and streets outside are clearly recognisable and the view does not turn into a mirror; turning the camera from outside to inside, the interior is hidden by the film’s reflection and only the skylight on the glass surface is visible.
See-through demonstration (customer experience)
That is what “one-way view-through” means: rather than plating the glass into a mirror at the cost of the view, it makes the direction of light differ by direction — the natural difference between bright outdoors and darker indoors in daytime is put to work by the film.
The customer, Mr. Li, standing at the window through the demonstration, gave the line captured in the video: “Insulation and see-through — better than expected.” That on-site reaction is recorded in full.
For project owners worried about “will it become a dark room after installation”, this demonstration is worth a look: beyond parameters, see-through performance is best confirmed in person at the window. The team can provide an on-site survey, demonstrating light behaviour at different times of day.
The full video is available on the company website and official short-video accounts.
