| Upkeep | Needs routine painting/staining | Low (wipe tidy) | Low (powder-coated surface) |
| Insulation | Exceptional thermal properties | Really great (multi-chambered) | Good (with thermal breaks) |
| Cost | Premium/Highest | Most inexpensive | Mid-to-high variety |
| Eco-Friendly | Sustainable and naturally degradable | Recyclable however synthetic | High recyclability |
Secret Qualifications to Look for in an Installer
