| Expense | Usually 30-50% more affordable than top quality lumber replacement. | High initial capital expense. |
| Durability | Initial slow-grown lumber can last another 100 years. | Modern timber varied; uPVC has a ~ 20-year life expectancy. |
| Thermal Efficiency | Exceptional with draught-proofing and slim-glazing. | Highest possible ratings with modern-day frames. |
| Ecological Impact | Low (utilizes existing materials). | High (production and disposal of old frames). |
