Which warranties, performance guarantees, and supplier qualifications are essential when procuring a glass curtain wall package?

Question

Accepted Answer

Buyers should request warranties covering glazing, coatings, hardware, sealants, and structural performance—typically ranging from 5 to 20 years. Performance guarantees must include tested compliance with air, water, thermal, and structural standards. Supplier qualifications include ISO certifications, past project experience, in-house engineering capabilities, and proven manufacturing quality control. Selecting a reputable supplier ensures long-term façade reliability and reduces project risk.
