I do not understand the other reviewers. We had this heat awning (in conjunction with a black out blind) on two skylights in the bedroom (southwest side). Heat reduction was almost 0. The thing perhaps holds a bit light, but no infrared radiation. Result: unbearable heat in the bedroom during the summer. I can not recommend to buy. Better to have a proper shutter outside the window, which, although more expensive, but keeps the heat outside and reliable.
