EnergyCore by Quanex Building Products
„„The EnergyCore window system uses fusion insulated frame technology that delivers energy savings 6 times better than fiberglass, 4 times better than rigid PVC, and 3 times better than wood. EnergyCore windows can deliver performance that exceeds the current ENERGY STAR requirements by 50%. The window has an air-cell insulating core that creates a thermal barrier. The tri-extrusion technology ensures that frame profiles are free of internal voids, using material that is corner-weldable and 100% recyclable.
