| Expense | Normally 30-50% less expensive than premium lumber replacement. | High preliminary capital outlay. |
| Sturdiness | Original slow-grown timber can last another 100 years. | Modern lumber differed; uPVC has a ~ 20-year lifespan. |
| Thermal Efficiency | Exceptional with draught-proofing and slim-glazing. | Highest possible rankings with modern frames. |
| Ecological Impact | Low (uses existing materials). | High (production and disposal of old frames). |
