How can a structural glazing facade maintain airtightness and waterproofing under extreme climate conditions?

A structural glazing façade maintains airtightness and waterproofing through multi-layer sealing technologies, redundant silicone barriers, pressure-equalized chambers, and engineered drainage paths. The primary structural silicone joint creates the airtight barrier, while secondary weatherproofing silicone protects against rain and wind infiltration. For regions with heavy rainfall or typhoons, dynamic water-penetration tests prove the façade can handle wind-driven water. Pressure-equalized systems balance internal cavity pressure, preventing water from being forced inward. Glass units incorporate edge seals resistant to moisture and UV degradation. For desert climates with intense UV exposure and extreme temperature swings, high-performance silicone with low modulus and high elasticity prevents cracking or embrittlement. In cold climates, anti-freeze design of drainage paths avoids blockage caused by ice. Proper condensation management ensures moisture does not accumulate inside cavities.
