Main Structure Material

• Wall thickness: 1.8mm, compliant with new national standards.

Sash Design

• Dual-cavity structure (indoor & outdoor), combined with 45° miter corner joining and glue injection technology, ensuring stable structure and high safety.

Frame Connection

• 90° connection process for easy processing; frame and sash are flush indoors and outdoors for aesthetic appearance.

Fixed Sash Reinforcement

• Multiple reinforced profile designs on the outdoor side, with high wind pressure resistance, suitable for various height divisions.

Functional Features

• Upper positioning wheel design for smooth sliding.
• 5mm translation locking for continuous sealing and excellent airtightness.
• Quick-install hardware for convenient installation.

Sealing System

• EPDM soft rubber strips for frame-sash sealing, with high deformation capacity to ensure sealing performance.

Size & Load Parameters

• Minimum sash width: 500mm
• Maximum width: calculated based on load-bearing capacity
• Sash height: calculated based on sash weight and wind pressure resistance
• Maximum sash weight: 100KG (with auxiliary wheels: up to 160KG)
  *Different sash heights, widths, and safety levels require matching hardware and profile configurations.
• Compatible maximum glass thickness: 39mm

Performance Grades

• Air tightness: Class 8
• Water tightness: 500Pa (with additional lock points at 350mm sash height)
• Wind pressure resistance: Class 9 (requires different reinforced profiles for different divisions)
• Thermal insulation: Class 6 (K value 2.0~2.5 with low-e insulating glass)
• Sound insulation: Class 4 (with insulating glass)
