HIGH INSULATION ERA IN SLIDING SYSTEMS
Nowadays, alongside energy resources, the importance of energy saving and efficient usage is also increasing. In building complexes, 82% of energy is used for heating purposes. This corresponds to 26% of the total energy consumed in our country. Of the heat loss in buildings, 40% originates from exterior walls, 30% from windows, 17% from exterior doors or balcony doors, 7% from the roof, and 6% from underfloor areas. This highlights residential units and insulation systems, particularly PVC window systems, as one of the most critical areas for achieving energy savings. The fact that energy is both the most limited and most expensive resource further emphasizes the need for “energy preservation,” i.e., insulation, in window systems.
Energy efficiency is a critical parameter for the sustainability of today’s buildings. High heat loss incurs significant costs in buildings. The Erpen Supportline Series offers a significant solution with its technical infrastructure aimed at minimizing these losses and achieving energy savings.
Supportline Series is produced in accordance with TS-5358 and EN 12608 standards and has quality certificates and test reports.
