Stained Glass Window Coverings Need Window Covering For Stained Glass Window?

Need window covering for stained glass window? - stained glass window coverings

We have a large window over the sink about 5 meters wide and 3 meters. It is a window of a church. The windows in the entire window, not just the top or sides. My dilemma is that there is a window to the west and I see that the summer heat comes only through this window in our house to keep warm. (we have no air conditioning) If you have any ideas for window coverings that are not keeping close to the window, but still contribute to the warm sunlight outside?
