Curtain Wall Industry Statistics

GITNUXREPORT 2026

Curtain Wall Industry Statistics

Prefab is already in use for at least one building element for 48% of respondents worldwide, a shift that aligns with a façade spend base expected to push the global façade systems market past $200B by 2030 and rising IGU demand, while performance standards for curtain wall design and verification are tightening around measurable structural, water, and thermal resistance. If you spec curtain walls, this page connects the policy push from energy use and emissions targets to the test methods and rating metrics that determine what actually passes, at the same time giving you current material and shipment scale from the latest aluminum framing and glazing market figures.
