I too have skylights (2) in a high ceiling that always generate a lot of unwelcome heat here in Indiana in the summer months, though fading has never been a problem.

After a lot of research, I ordered some Phifer Suntex Super Solar 90 Sun Screen fabric (by the yard)....see link below. So far, I have only affixed it temporarily to the outside of one of the windows, but I believe it has made a big difference. The sun no longer shines on the carpet, making the carpet itself feel warm to the touch.

Have you maybe checked with a local window place to see if they could maybe make you some exterior screens? I talked to my local window place and he said the solar screen was so thick and stiff that he couldn't say for sure if he could put it in a frame or not. Then too, I don't know of any easy way to affix the screen frames on the outside even if he could make them. That is why I just temporarily covered one window and think I'll be able to remove it just fine when the temps cool and I welcome the sun generated heat.

If you would like, I can send you a scrap piece of the material, that you could then check with a local window place to see if they could put it in some frames for you. Affixing the frames to the windows, might also be a problem for you too though. I just used six 1/2" squares of double faced stickums, and those have held it in pace just fine for a couple weeks now. The frames on the outside are about 2" wide and the screen is very rigid.

Drop me an email if you'd like a sample piece. Please put skylight or something similar in the email subject line, as I don't open anything that looks unfamiliar or suspicious.
