What should I look for when selecting a curtain wall manufacturer?
When selecting a curtain wall manufacturer, evaluate six critical areas: manufacturing capability, engineering expertise, quality assurance, project experience, service and support, and financial stability.
Evaluation Checklist
1. Manufacturing capability
- Factory size and production capacity (can they handle your project volume?)
- In-house aluminum extrusion vs. purchased profiles (vertical integration = better quality control)
- Glass processing capabilities (tempering, laminating, IGU assembly)
- Unitized panel assembly lines (for unitized systems)
2. Engineering expertise
- In-house structural engineering team
- Ability to provide shop drawings and structural calculations
- System testing capability (air, water, structural, seismic)
- BIM coordination capability
3. Quality assurance
- ISO 9001 certified quality management system
- Material certifications (aluminum, glass, sealants, hardware)
- Third-party testing reports (ASTM, EN, AAMA standards)
- In-house QC inspection at each production stage
4. Project experience
- Track record in your project type (residential, commercial, public)
- Experience in your target market (export experience, code compliance)
- Reference projects with customer contacts
- Ongoing project visibility (factory tours, site visits)
5. Service and support
- Early design involvement and value engineering
- Installation guidance and on-site technical support
- Warranty terms and post-installation service
- Communication responsiveness and English-language support
6. Financial stability
- Company history and ownership structure
- Production capacity utilization
- Ability to handle payment terms for international projects
