How are thermal breaks and framing materials selected to reduce condensation risk in a glass curtain wall?

Thermal breaks are essential for reducing heat transfer through aluminum framing in glass curtain walls. Without them, interior surfaces may reach dew point temperature, leading to condensation. Manufacturers use polyamide strips or advanced resin materials to separate interior and exterior metal components. This significantly improves thermal resistance and condensation control. Frame selection considers regional climate, interior humidity, and building use. Hospitals, laboratories, and swimming facilities require stricter condensation prevention strategies. Engineers also evaluate curtain wall geometry, insulation continuity, and glazing selection. Low-E coatings and warm-edge spacers in IGUs further minimize condensation. A properly engineered system ensures long-term comfort, energy efficiency, and prevention of moisture-related damage.
