Recurring water leaks in stick-system curtain walls leading to rework? Here's an essential guide for contractors to avoid costly pitfalls.

Construction contractors are most troubled by the perennial issue of stick-system curtain walls—“repaired every year, yet still leaking”—which stems from hidden problems in the three key areas: framing, glass, and sealing.
Key product selection strategy: The frame must be "deformation-resistant"—choose 6063-T6 aerospace-grade aluminum alloy with a wall thickness of ≥3.2mm and crossbeam stiffener spacing ≤600mm to prevent deformation under wind pressure.
Glass needs to be "strongly adaptable"—choose configurations based on the region: use 6+12A+6 double-silver Low-E insulated glass in typhoon-prone areas, and opt for the 6+20A+6 argon-filled version in northern regions with severe cold.
Sealing requires "double insurance"—using a dual-seal system of "structural adhesive + weather-resistant adhesive," with adhesive joint widths of at least 15 mm, and conducting peel tests to ensure there’s no delamination.
When making purchases, check the profile mechanical testing report and conduct on-site water-tightness spray tests—refuse to accept merchants' practice of downgrading by using standard aluminum profiles instead.
Suitability: Choose fluorocarbon-coated frames for office buildings, and anodized frames for shopping malls.
