HIGHLY INSULATED ERA IN SLIDING SYSTEMS
Today, the importance of energy conservation and efficient use is increasing, as is the importance of energy resources. In building complexes, 82% of the energy used for heating purposes. This figure corresponds to 26% of the total energy used in our country. 40% of heat loss in buildings originates from exterior walls, 30% from windows, 17% from exterior doors or balcony doors, 7% from the roof, and 6% from slabs. This highlights homes and PVC window systems as one of the most important areas for energy savings. The fact that energy is the most limited and expensive resource makes “energy conservation,” or insulation, even more important in window systems.
ComfortLine, thanks to its high-performance insulation values, meets energy efficiency standards. Its multi-chamber structure and special glass combinations consume less energy, thereby both reducing heating and cooling costs and ensuring an environmentally conscious usage.
ComfortLine series is manufactured in compliance with national and international quality standards:
These certificates demonstrate the reliability of ComfortLine window systems in terms of both durability and energy efficiency.
ComfortLine can be used safely in all structures where thermal insulation, silence, and aesthetics are sought together. It offers a wide range of applications, from residential projects and office buildings to villas, modern living spaces, and commercial buildings.
