| Sturdiness | Original slow-grown lumber can last another 100 years. | Modern lumber differed; uPVC has a ~ 20-year lifespan. |
| Thermal Efficiency | Excellent with draught-proofing and slim-glazing. | Greatest possible ratings with contemporary frames. |
| Environmental Impact | Low (utilizes existing materials). | High (production and disposal of old frames). |
