, first time poster here.
i have a large south-facing dining room window that we installed "heat control" window film that "reflects 70% of summer heat" and "99% UV rejection".
does this qualify as "no direct sun"?
I am afraid I don't know the answer to that, but I had it on my east facing windows( it is a big bay window), and I did take it off. I have my phals there and I thought they needed more light in the winter.
Well, the light is not bright and they only get sun in the mornings. I know not to put them outside in the full sun, but have not had any problem this way. Someone else could probably give you better information on this.
It depends on what type of orchids you grow. I also live in central New Jersey and I grow cattleyas. They are in my south facing picture window as close to the glass as I can get them without touching it. The window has the inner glass and the outer insulated windows and they grow and bloom fine. When I also grew phals they were behind the catts.
Do you have photos of the window/plants on a sunny day? That would give me more of an idea, since I've never heard of these films before. What kind of orchids do you have there?

I don't think you will be able to see the tint on the windows. It is like tinted windows on a car. It does come in different tints, some darker than others. Mine was not as dark as my tinted windows on my car, but helped filter out the heat from the summer sun.
