The 80 Series Inward/Outward Opening System Windows merge aesthetic appeal with robust functionality. Featuring a flush frame-sash design and seamless welding, they offer enhanced structural integrity. Equipped with Xinyi glass (argon-filled) and triple EPDM seals, these windows provide superior thermal insulation, noise reduction, and water resistance. Available in multiple opening modes (inward, outward, tilt, or top-hung), they are suitable for balconies, bedrooms, and sunrooms. The PA66GF25 thermal breaks and corrosion-resistant hardware ensure long-term durability, while the minimalist design complements contemporary architectural styles.
