| Lifespan | 25 - 35 years | 50+ years (with stringent maintenance) |
| Resistance to Elements | Impervious to rot and bugs | Prone to rot, warping, and swelling |
| Thermal Efficiency | Excellent (Multi-chambered) | Good (however vulnerable to drafts gradually) |
| Authenticity | High (with woodgrain foils) | Authentic (Original) |
