Bulky Traditional Frames: Obstruct natural light and conflict with modern minimalist interior designs. Ultra-Slim Profile: Minimalist narrow frame design increases light intake by 30%, perfectly matching modern aesthetics.
Poor Sealing Performance: Outward-opening windows are prone to water leakage and air infiltration during heavy rain. Triple Sealing System: Utilizes three layers of imported EPDM sealant strips to achieve top-tier watertightness and airtightness standards.
Short Hardware Lifespan: Frequent operation often leads to loose handles and rusted hinges over time. Imported Hardware: Equipped with imported hardware supporting 100,000+ trouble-free opening cycles; hardware customization available.
Safety Risks: Concerns about windows falling from high-rise buildings or children accidentally opening them. Safety First: Standard anti-fall cable design combined with hidden built-in child locks to ensure absolute family safety.
