Quanex EnergyCore Fusion-Insulated Windows
Quanex’s AirCell insulation protects the elements of the EnergyCore product line, which has expanded to include horizontal sliders, tilt single-hungs, side-load single-hungs, and corresponding profile picture window designs. The insulation is isolated for sash weeping, with a new fixed-interlock with triple weather-stripping contact points. All EnergyCore items accept 3/4-inch dual-pane IGs and triple IGs up to 1 1/8 inch.
