Opera Job Management manages the performance of blackout windows and doors, both for jobs related to Shutters only, and for those related to Frames and Shutters. Let's see what procedures to follow in either case.

Job order that includes only Shutters

  • Select the shutter in the job order and open the General Data Type panel.

  • Match the EN 14501 standard
  • Enter under 'Solar transmittance, the property of the shutter indicated
    • Opaco
    • Traslucente medio
    • Molto traslucente
Note N.B: These properties indicate how much solar energy is transmitted through the product under investigation. With a shutter with adjustable slats we can associate a solar transmittance opaque when the closed slats do not allow solar energy to pass through; in the case where there is passage of solar energy then we speak of translucence.


  • After recording the Solar transmittance' we re-enter the General Data Type panel and select the File:Shade Key.png ; the Shading type panel will open.

Within this framework we can define:

Note N.B: If the field Matched glass type is not filled in by choosing from the matched menu, the fields Ug (Thermal transmittance of glass mounted on existing window frame) and g (Solar factor of glass mounted on existing window frame) will be activated where, if known, it will be possible to specify the glass data.
