I will upload the picture and you will see the windows at the peak of the house and the mechanical room. I also will upload the back as there are 2 windows there as well. I have sheers at the bottom which are fine but the top windows let in so much heat that even the air conditioning cannot handle it.Answer
You most likely need a room darkening solution if you want to block the heat. Roman shades, shutters, and room darkening cellular shades can be made in this shape. The upper triangle will however always be closed, so the purpose of this shade will be light and heat blocking but will not allow you to look out of this window.
If you want to match your sheers, you can try our sunburst kit. But using sheer fabric will not block enough heat.
The only window covering that will allow you to to open and close as needed, so that you block the sun when needed and have your view when you want, is our operable cellular shades. They come in room darkening and light filtering versions.
Unlike other cellular shades these will open and stack up to the angled top not only until where the angle starts.
