| Sturdiness | Original slow-grown wood can last another 100 years. | Modern timber varied; uPVC has a ~ 20-year life expectancy. |
| Thermal Efficiency | Exceptional with draught-proofing and slim-glazing. | Greatest possible scores with modern frames. |
| Environmental Impact | Low (utilizes existing products). | High (production and disposal of old frames). |
