US English - The windows are made of glass. It took me a few moments to figure out what you meant because I would never say that the windows are made of wood. The window frames may be made of wood or plastic or something else (mine are made of metal). But we would always say "window frames" when talking about the thing that surrounds the area you look through.

I have aluminum framed windows. An upper and lower window per window opening and each window is a solid pane of glass. I have curtains the I bought at Ikea.

Our windows are made of wood. They do not have panes. They slide up and down, both top and bottom portions. I use curtains in some windows, and blinds in others.

Thanks a lot!

Some frames are kvinyl frames, not plastic. But I think they stopped making vinyl ones years ago. But I'm not sure. They were not of good quality, generally.
