1. Confirm local building code requirements for wind resistance, fire rating and energy efficiency standards for your region first

3. Request sample materials and performance test reports from at least 3 qualified suppliers for cross comparison
4. Check supplier’s post-installation warranty policy, confirm coverage for hardware accessories and seal parts
5. Verify the supplier has local professional installation teams rather than outsourcing to third-party unvetted workers
6. Lock in your order 4 to 6 weeks before your construction timeline to avoid 2026 global supply chain delays for custom profiles
