In glass-curtain-wall projects at design institutes, three requirements are often raised at once: shading and insulation, daytime daylight, and a clear outdoor view. The video breaks them into three dilemmas and presents each in turn.
Dilemma one: insulation without a view. Film-based solutions that mainly work by reflection stop solar heat but turn the glass into a mirror — lights stay on indoors during the day and the outdoor view is “plated” away. Dilemma two: shading without insulation. Roller and blackout blinds tame glare but cannot stop radiant heat that has crossed the glass; the temperature behind the blind stays the same. Dilemma three: all three at once. In conventional practice these goals pull against each other, and selection means making a trade-off.

The video also notes a trend: more design institutes are now evaluating insulation, shading and see-through as one integrated dimension at the project stage, rather than splitting them across disciplines.
In the video, Zhongke Energy Consumption Control presents the corresponding approach — the ESEC One-Way View-Through Energy-Saving Window Curtain: it handles solar radiant heat by reflection, reflecting 88% of it back; keeps a clear view from indoors to outdoors during the day; and is mounted on the inner side of the glass without altering the curtain wall itself.
For project owners making a selection, the video offers three criteria: whether the material handles heat by reflection or absorption, how it performs in daytime see-through, and how its installation affects an existing building.
