InsulKor™ technology is a system of sash and frame enhancements that dramatically improves the performance of the eXtreme 8000 double hung window. Our exclusive InsulKor fiberglass-enriched polyurethane sash reinforcement yields better energy efficiency while maintaining the structural integrity of traditional metal reinforcement. The optional InsulKor foam injections add thermal-enhancing insulation in specific hollows of the frame. The combination of foam-filled and dead air chambers optimizes each window’s thermal properties for exceptional R-values. When combined with either of our R-5 rated, triple-pane glazing systems, these InsulKor enhancements help make the eXtreme 8000 one of the most energy efficient, strongest window systems available today.
