EnergyCore

The EnergyCore Fusion Insulated System™ combines superior vinyl framing technology and triple-pane glass, resulting in an energy-efficient window that exceeds ENERGY STAR® and DOE R5 efficiency requirements.

To achieve this high level of efficiency, EnergyCore windows incorporate the patented AirCell™ technology, a special foam-fill that provides a complete air barrier within the vinyl frame.  Depending on the glass application, EnergyCore windows can increase your window efficiency by up to 50 percent.
