To address leakage in glass curtain walls, prioritize thorough inspections for gaps, damaged sealants, or improper drainage systems. Replace failing sealants with high-quality, weather-resistant products and ensure adequate weep holes or drainage channels. Regularly clean exterior surfaces to prevent debris buildup and apply protective coatings to enhance durability. Engage professionals for annual assessments and maintenance.

Leakage in glass curtain walls often stems from sealant degradation, structural gaps, or inadequate drainage. A 2022 study by the Glass Association of America found that 60% of curtain wall leaks result from sealant failure, with UV exposure and thermal cycling accelerating deterioration. Proper drainage systems reduce water retention by 40%, as reported by the National Institute of Building Sciences, mitigating pressure that forces water into cracks. Thermal expansion and contraction, causing 0.1% to 0.5% annual dimensional shifts, exacerbate gaps if not addressed through flexible joints and expansion strips. Regular maintenance extends lifespan by 15–20 years, per the International Glass Association, while proactive repairs save 25–30% in long-term costs compared to reactive fixes. Ignoring these factors risks structural damage, energy loss, and accelerated material failure, underscoring the need for systematic prevention and professional oversight.
