EnergyCore™ Fusion Insulated™ window system – an innovative, patent-pending energy-saving technology

The EnergyCore system offers superior performance to meet homeowners’ need for more energy-efficient windows. EnergyCore’s Fusion Insulated technology utilizes an innovative, engineered AirCell™ insulating core, designed to create a superior-performing thermal barrier. It also features a thermally-fused tri-extrusion manufacturing process to ensure frame profiles are fully insulated using a weldable, 100% recyclable material.

To deliver the ultimate energy-saving performance, the EnergyCore system combines these superior thermal performing frame profiles into a system designed to accept the best-performing triple-pane insulated glazing, such as those that use Duralite® warm-edge spacers.
