A Better Way to Control Heat Gain & Sun Glare
Yonatan Zvi Margalit envisioned a smarter solution to managing heat gain and sun glare. Drawing on his background in facade innovation, he designed a system using specialized film—an idea brought to life through a working mock-up. This video captures the concept in action, showcasing a practical and elegant approach to daylight control.
But what you see is only the beginning. His method goes far beyond glare reduction—it reimagines the entire build process, streamlining construction, skipping unnecessary steps, and introducing efficiencies that simply wouldn’t exist without thinking far outside the box. The result? A breakthrough in both performance and practicality.
