| Sturdiness | 60+ years (with upkeep) | 25-- 35 years | 40+ years |
| Upkeep | Needs routine painting/staining | Low (wipe clean) | Low (powder-coated finish) |
| Insulation | Excellent thermal homes | Excellent (multi-chambered) | Good (with thermal breaks) |
| Cost | Premium/Highest | A lot of budget-friendly | Mid-to-high range |
| Eco-Friendly | Sustainable and naturally degradable | Recyclable however synthetic | High recyclability |
Key Qualifications to Look for in an Installer
