Energy Star Partner

The series 3000, 6000, and 9000 windows are performance-engineered for advanced energy savings. Quality-crafted frame and sashes, heavy-duty multi-layer weather-stripping, airtight insulating chambers, compression bulb seal and the PPG Intercept® Warm-Edge Spacer System together help block air infiltration for reduced heating and cooling costs.

For even greater energy savings, choose Gentek windows with one of our BarrierXP® insulating glass packages. BarrierXP combines multi-layer low-emissivity (Low-E) glass and argon gas along with the PPG Intercept Warm-Edge Space System for maximum energy savings. Many BarrierXP insulating glass packages meet the latest ENERGY STAR® requirements. Consult your window professional for the optimal glass package required for your home and climate zone.

ENERGY STAR is a government-backed voluntary partnership program sponsored by the U.S. EPA and the U.S. DOE, which promotes environmental protection and superior energy efficiency in products, buildings and homes.

An average household spends more than 40% of its annual energy budget on heating and cooling costs. Gentek windows with BarrierXP insulating glass are over 50% more energy efficient than clear glass units.
