High-rise buildings often encounter issues such as poor prefabrication accuracy, installation misalignment, and inadequate sealing that leads to water leakage when purchasing unitized glass curtain walls. These problems not only delay the construction schedule but also increase costs.
The core of unitized curtain walls lies in the precision of factory prefabrication and their adaptability to on-site installation, with high-quality unit panels maintaining dimensional tolerances of ≤1mm. Key procurement controls include: first, reviewing the prefabrication report to ensure that panel flatness and diagonal error meet the specified standards.
Second, test the sealing performance by conducting a water-tightness test to ensure no leakage occurs even in heavy rain conditions. Third, verify the compatibility of components—ensuring that connectors perfectly match the main structural elements and meet the required standards for corrosion protection.
Suitable scenarios: For super-tall buildings, choose energy-efficient units equipped with thermal channels; for coastal areas, opt for enhanced models capable of withstanding typhoons up to Category 12. Note: Manufacturers are required to send technical personnel to provide on-site installation guidance, ensuring proper setup and preventing potential hazards caused by incorrect installation.
