Job order that includes only Shutters

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

• We choose the color for the shutter and in theColor Archive and set for the color the Reflectance Type

• Select the File:KeyData5.png button to open the "Type Data in the Job Order" panel and the File:KeyCE.png button to access the normative data panel

• Match the EN 14501 standard

• Enter under 'Solar transmittance, the property of the shutter indicated
  • Opaco
  • Traslucente medio
  • Molto traslucente

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:

• the Obscuring position

• the Matching glass type using the glass specified in UNI EN 14501, recorded in the list.

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.
