| Toughness | 60+ years (with upkeep) | 25-- 35 years | 40+ years |
| Maintenance | Requires routine painting/staining | Low (wipe tidy) | Low (powder-coated surface) |
| Insulation | Excellent thermal properties | Very great (multi-chambered) | Good (with thermal breaks) |
| Cost | Premium/Highest | Many affordable | Mid-to-high variety |
| Eco-Friendly | Sustainable and naturally degradable | Recyclable but artificial | High recyclability |
Key Qualifications to Look for in an Installer

List for Vetting Installers:
- Do they use an extensive study before supplying a final quote?
- Are the windows "A-Rated" for energy effectiveness?
- Do they offer a clear timeline for the task?
- Are elimination and disposal of old windows included in the price?
