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.
