Hi renotalk, I'm looking at doing a window between the study room and living room, which can be opened, but is still good for watching TV when the windows are closed. I wonder if anyone here knows if there's any of such vertical sliding or guillotine style windows in Singapore? I considered glass partitions, but there's still vertical lines, hence would not be as ideal as the vertical sliding windows, but I guess if I can't find any I would have to settle for the partition-style windows.
