Sound insulation windows

High sound insulation even when the window is open? WICONA has found a solution for an issue that at first appears irresolvable – the WICLINE 215. A double pane window with the same structural and physical values of a double skin façade. This new type of window combines an inward opening sash with a parallel projecting sash. Both can be operated independently. This construction multiplies the user comfort in many ways: individual ventilation, and automatic control for night cooling assure the best possible room climate. A sun protection device integrated between both sashes not only ensures even greater comfort, it also reduces energy consumption.

Technical performance

System technology:

  • Hybrid window in double skin technology, with all ist advantages: interior manual or automatised sash, exterior parallel outward opening sash
  • Two sashes that can be operated individually, no restrictions in use
  • Integrated sun shading device, protected against high wind speeds, dirt and weathering
  • Only 215 mm system depth, despite integrated solar protection, motor assistance and control system
  • Inner sash protected from burglary or weathering even when outer window is open

Thermal insulation:

  • Uw values until 0.65 W/(m²K) are feasible

Sound insulation:

  • Superior sound insulation level with closed sashes, depending on the glazing; increased sound insulation already with open exterior and interior sash
  • In combination with sound insulation glazing a protection level of 57 dB can be achieved


  • Interior sash with following options:
    • turn
    • turn-tilt/li>
    • tilt/li>
    • double casement/li>
    • E-TecDrive/li>
    • fanlight/li>
    • burglar resistance/li>
    • night cooling
