Test Your Knowledge: Framing Design & Performance in Glass Curtain Walls

This week’s quiz is from Glass curtain walls: Framing design and performance. Glass curtain walls are shaping modern façades with expansive views, daylight access, and stronger building envelopes—but the performance lies as much in the framing as in the glass itself. From steel’s structural advantages to thermal efficiency and air/water control, see how well you understand the design and performance trade‑offs that drive curtain wall systems in today’s high‑performance buildings.
