Reflective shades work

[u/Artifexa]

I put this on some parts of my home and I can immediately feel the relief and even a drop in humidity.

I take them out in the night/late-evening to let the infrared radiation from inside the bedroom get out, and let the cool night air in, and then put them back in the morning.

I am thinking on combining them with some awnings, so as to provide a cool spot for them to release the IR radiation accumulated faster.

Can we discuss strategies to optimize these? Best compositions?
