Product Features
Space-Optimized Vertical Folding Design The window features a top-bottom folding mechanism that stacks fully into overhead tracks, achieving 100% open space without indoor/outdoor footprint. Ideal for compact kitchens or sunrooms, it creates a seamless "frameless" transition between interiors and exteriors, maximizing natural light and airflow while eliminating traditional swing-out obstructions. The vertical fold preserves wall space for furniture or décor. | Gear-Driven Lift System with Anti-Sag Precision Equipped with a hydraulic-free synchronized gear mechanism, the dual-side lift system ensures smooth, wobble-free operation at any height. Engineered with 6063-T5 aerospace-grade aluminum and industrial-grade bearings, it supports up to 50kg/sash without drooping, even after 50,000+ cycles. Self-locking teeth provide secure positioning, ideal for commercial spaces requiring frequent ventilation adjustments. |
Aesthetic Versatility & Low Maintenance Customize with 8 fade-resistant finishes, including woodgrain (Huanghuali/Yellow Sand) and fluorocarbon metallics (Red/Matte Green), via electrostatic spraying. The seamless, radius-free edges and automotive-grade EPDM seals resist dust accumulation, while the hydrophobic aluminum surface enables rainwater self-cleaning. Corrosion-resistant coatings eliminate repainting needs, reducing lifetime upkeep costs by 60% vs painted steel. | Cost-Efficient Non-Thermal Break Structure Designed for mild climates or budget-conscious projects, the non-insulated aluminum profile cuts costs by 30% versus thermal break models while maintaining durability. Its lightweight yet rigid foldable frame suits high-traffic areas like cafes or retail stores, offering quick installation and modular repairs. Optional tempered glass (5-10mm) balances affordability with safety compliance (IGCC&AS 4666 impact-rated). |
