Conventional single glazing and the intrinsic gaps needed for sash windows to move efficiently result in considerable heat loss. This often leads to a cold living environment and high energy expenses.
3. Paint Seizure and Rattle
Years of over-painting can cause windows being "painted shut." On the other hand, wood shrinking over a century can trigger sashes to fit loosely in their frames, leading to annoying rattles during windy weather condition.

| Thermal Efficiency | Significantly improved through seals. | Exceptional (Modern requirements). | Exceptional for acoustic/thermal. |
| Life-span | 20-- 40 years with upkeep. | 30-- 50 years. | 10-- 20 years. |
| Preparation Permission | Typically not needed (Maintenance). | Frequently required in Heritage locations. | Sometimes required for noted. |
| Expense | Moderate. | High. | Low to Moderate. |
