Insulated Glass Packages

Reducing energy loss is often the number one reason for purchasing replacement windows. Windows are roughly 80% glass, so it’s important to choose the ideal glass system for your home and climate. Upgrading to a high-performance Low-E (low-emissivity) insulated glass package may help further increase year-round energy savings.

As of October 23, 2023, the ENERGY STAR 7.0 program implemented more stringent energy-saving criteria for windows and doors, with lower U-Factor and Solar Heat Gain Coefficient performance requirements. Alpine windows and sliding patio doors offer a variety of SolarTherm insulated glass packages that meet new ENERGY STAR 7.0 certification in all climate zones.
