You can get wall insulation that is, effectively a stiff bubble wrap made of milar foil. It’s not even that expensive I cut it to match windows, then used suction cuts to fix it in place.
It’s amazingly effective at keeping heat out. During the 45 degree weather, I barely had to use my air conditioner, to have a comfortable temperature.
The film allows you to still see out and get a bit of light and doesn’t result in your house looking like a drug den. I am aware of the foil though. How does it compare to tinfoil on cardboard?
I’ve not tried tin foil. The insulation seems to be more robust, and it wants to lie flat. It’s also optimised for IR reflection, tin foil isn’t.
Downside, it’s a near perfect blackout material. I only put them up when it’s going to be ridiculously hot, and only on the sun facing side of the house.

Might give it a try, wonder how long before my cat decides its a scratch toy though. Another benefit to external window films.
