| Home Value | Boosts value by maintaining heritage functions. | Can devaluate listed or duration properties. |
| Life expectancy | 50+ years with small upkeep. | 20-- 30 years (uPVC degrades in sunlight). |
| Environmental Impact | Low-- reuses existing products. | High-- manufacturing and disposal of plastics. |
| Thermal Efficiency | Exceptional with modern draught-proofing. | Exceptional, however often visually compromised. |
| Regulative Compliance | Typically authorized for Grade I & & II noted buildings. | Frequently rejected by preservation officers. |
