This virtually removes rattles and substantially decreases heat loss without altering the window's appearance.
Glazing Upgrades

| Thermal Efficiency | Substantially improved by means of seals. | Exceptional (Modern standards). | Exceptional for acoustic/thermal. |
| Life-span | 20-- 40 years with upkeep. | 30-- 50 years. | 10-- 20 years. |

| Cost | Moderate. | High. | Low to Moderate. |
