Erpen Premium66 is a robust and aesthetic window solution that offers high insulation in sliding systems. With a 66 mm profile thickness, it delivers balanced performance regarding thermal, acoustic, and air permeability. It has been developed to meet the expectations of modern architecture and the requirements of sustainable construction.
Today, the importance of energy conservation and efficient usage is growing alongside the significance of energy sources themselves. In building complexes, 82% of energy consumption is dedicated to heating; this figure accounts for 26% of the total energy used in our country. Heat loss in buildings stems from various sources: 40% through exterior walls, 30% through windows, 17% through exterior or balcony doors, 7% through the roof, and 6% through the flooring. Consequently, residential buildings—and PVC window systems as a key insulation solution—emerge as critical areas for achieving energy savings. The fact that energy is the most limited and costly resource places a greater emphasis on “energy conservation”—that is, insulation—within window systems.
