VWS70 Awning Window

Aluminium system windows but reach passive house windows standard (U≤1.0W/(㎡·K) with the help of vacuum insulating glass.

High strength,hardness,toughness to ensure windows overall safety performance.

  • 29% higher tensile strength than 6063-T5.
  • 23% yield Strength than 6063-T5.
  • 7% higher Vickers hardness than 6063-T5.
  • 13% maximum percentage elongation than 6063-T5.

Vacuum Insulating glass, maximum eliminate the heat transfer through convection and conduction,HVIG realize Max 0.35W/(㎡·K) ,increase windows thermal performance significantly.

  • Double glazing unit U value 1.6W/(㎡·K)
  • Tripe glazing units U value 1.2W/(㎡·K)
  • Hybrid vacuum glazing unit U value 0.35W/(㎡·K)

Technoform thermal bridge is made with poyamide 6.6 with 25% fiberglass reinforcement to ensure high impact resistance and excellent thermal performance.

Automobile level EPDM rubber,low heat transfer coefficient,better air tightness.

Flush sash design keep simple and beautiful,increase airtightness,watertightness and structural performance.

  • Watertightness 720pa
  • Airtightness 0.10 L/s·m2
  • Structural Performance AAMA-PG50
