Opaque rooflight (no glass)

[PierNick]

Hi,

I am trying to model natural ventilation using a rooflight with the same construction layers of the roof, because I don't want solar gain.

How can I assign a different material than glass to the rooflight? Should I add a shutter always low?

Thank you so much

Hi,

In this instance we'd recommend you model it as a door rather than window. This is a common solution where MacroFlo is concerned but you want to keep the opening opaque.
