AFAIK this is not possible. When you pipeline your vtkPolyData through a 
vtkPolyDataMapper and finally a vtkActor, there is just one 
vtkProperties associated with the actor where you can set the opacity.

We too have a dataset with windows in it (actually it is a building) and 
we will put walls and windows in different actors. If you find an other 
way please let me know.
