| Thermal Insulation | Exceptional (U-values significantly enhanced). | Exceptional (Standard 1.2 - 1.6 U-value). |
| Planning Permission | Hardly ever needed; perfect for listed structures. | Typically required in preservation areas. |
| Expense | Usually more economical. | High preliminary financial investment and labor costs. |
