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.

Thanks to these features, the Extraline profile is a strong choice for both performance and long service life.
Today, the energy efficiency of buildings has become highly critical. A major part of building energy losses occurs through glass and window surfaces. Extraline profiles aim to increase thermal insulation by reducing heat losses. In this way, they provide significant savings in heating and cooling costs.
Extraline is produced in compliance with TS-5358 / EN 12608 standards and supported by quality certificates and test reports. All documents and reports related to the product can be downloaded in PDF format from our website.
