Can't see plane through window


I'm glad that you solved your problem.

As you had some problems with the orientation of faces, I just remembered something that I posted in this thread:
reply #5, that will make it much easier to know which way a face is oriented.

If you do this using File->New, then you can use the File->Save As Template... option with Set as default template checked. The next time you start to make something, you will have some color that you can't miss to let you know which side of the face you are looking at.
