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.
Energy efficiency is a critical parameter for the sustainability of buildings today. High rates of heat loss result in significant costs for buildings. The Erpen Supportline Series offers a key solution in this regard, featuring a technical design aimed at minimizing such losses and achieving energy savings.
The Supportline Series is manufactured in accordance with TS-5358 and EN 12608 standards, and quality certificates and test reports are available.
