In St. Louis, the summers are hot and humid, and the winters are cold. Therefore, you need window glass that will keep your home’s interior temperature comfortable, no matter the weather outside. Double-pane glass is an excellent insulator and popular among homeowners for its relative affordability. Triple-pane glass offers additional insulation but comes at a premium.
Low-emissivity, or low-E glass, can keep your home well insulated while also offering UV protection. Finally, tempered glass may be worth considering as it can hold up better to impacts, such as tornadoes or other storm debris.
| Glass Type | Average Cost per Window |
|---|---|
| Tempered | $200–$500 |
| Double-pane | $200–$2,000 |
| Triple-pane | $1,000–$4,000 |
| Low-E | $300–$1,100 |
