How does a structural glazing facade compare with traditional curtain walls in durability and performance?

Structural glazing façades exceed traditional curtain walls in aesthetic continuity, airtightness, thermal efficiency, and movement accommodation. The absence of exterior caps produces a smooth, uninterrupted façade that resists weathering. Structural silicone improves resistance to building sway, thermal expansion, and differential movement. Traditional systems rely heavily on gaskets and mechanical fasteners that degrade over time, requiring more maintenance. Structural glazing reduces air leakage and improves waterproofing due to continuous seals. While conventional curtain walls may allow more flexibility in immediate glass replacement, structural glazing’s bonded system provides superior long-term durability, energy savings, and wind-load resistance.
