Core Features

1. Invisible Engineering, Maximum Functionality
   • Fully Concealed Tracks: The sliding hardware and lower track are integrated into the frame, eliminating visible components for a clean, minimalist look.
   • Flush Surface Design: Sashes align perfectly with the frame when closed, reducing air resistance and dust accumulation (aerodynamic coefficient: ≤0.3).
2. Advanced Thermal Break Technology
   • PA66GF25 Insulation Strips: Multi-layered nylon strips break the thermal bridge, achieving a U-value as low as 1.2 W/(m²·K) (with triple glazing).
   • Energy Savings: Reduces heating/cooling costs by up to 40% compared to traditional aluminum windows.
3. Heavy-Duty Structural Integrity
   • 6063-T5 Aluminum Alloy: High-strength frame with stainless steel reinforcements in load-bearing areas (e.g., large sash supports), capable of supporting 120 kg per sash (max size: 2.5m × 2m).
   • Wind Resistance: Class 8 (EN 12211, withstands 2.0kPa pressure), suitable for high-rise buildings and coastal regions.
4. Quiet and Weathertight Operation
   • Precision Pulleys: Premium HOPPE or OPK rollers with dual-ball bearings ensure smooth sliding at <45 dB noise level.
   • Quadruple Sealing System: EPDM rubber gaskets provide an IP65 waterproof rating (no leakage under 250Pa water pressure).
5. Customizable Aesthetics
   • Finish Options:
     • 200+ RAL powder coat colors (matte, metallic, or suede textures).
     • Anodized finishes (25μm thickness, the salt spray test for 1,000 hours).
   • Dual-Tone Design: Different interior/exterior colors (e.g., white inside, graphite outside) for personalized style.
6. Safety and Security
   • Standard Glazing: 5+20A+5 Low-E double glazing (sound reduction: 32 dB).
   • Upgrades:
     • Laminated glass (EN 356 Class P4A, impact-resistant).
     • Concealed multi-point locking system (3–5 points per sash).
