Key Features & Benefits
1. Multi-cavity structure profiles (bridge cut aluminum) effectively block thermal conduction, significantly improving insulation.
2. Multi-channel sealing design (three seals) tightly fills gaps between the window sash and frame, preventing sound leakage and external noise.
Utilizing a 45° diagonal joint with corner code injection glue for superior durability:
1. High Structural Strength: Resists deformation and wind pressure.
2. Ultimate Sealing: Blocks air and moisture from corner joints.
3. Weather Resistance: Avoids noise and looseness from thermal expansion.
- Corner Protectors: Effectively avoid harm to children and adults from sharp internal fan angles.
- HOPO Hardware: High-strength aluminum and stainless steel components with multi-layer electroplating for corrosion resistance.
- Concealed Drainage: Rainwater is discharged outward while improving air tightness and aesthetic appearance.
