What should I look for when selecting a curtain wall manufacturer?

When selecting a curtain wall manufacturer, evaluate these critical factors:

**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
