The experiment found the indoor temperature of the house with yoghurt on the windows was on average 0.6C cooler, but up to a maximum of 3.5C cooler when it was "hot and sunny".
What the fuck kind of experiment is this? Putting anything white on the windows will cool the house like that.
More propaganda from the dairy industry.
The thick layer of wasps and flies on the yoghurty windows would also help.
He told the BBC the yoghurt smells for "30 seconds when drying" but that as soon as it has dried "the smell disappears".
I suppose I could paint my windows with yoghurt. Or, and hear me out: I could eat the yoghurt and invest in some white curtains.
Sun films have been available commercially for a long while. Choose how much sunlight you want reflected (generally more in bedrooms that you generally want dark and cool, less in rooms where you want a view), and either get a professional to apply or do it yourself—it just takes a bit of soap water and effort.
Generally better to have the sun rejection happen on the outside of the window, so as little as possible energy gets absorbed.
But you can't wipe it off as easily as moldy yoghurt
What should you look at with choosing which film to get? Some mention more about insulating to keep heat during winter. I am mainly looking to reflect thermal energy during summer.
I'd go with a 3M product. Unless their quality has suddenly taken a shit, they're best in class for that kind of thing. You want quality film because removal is an awful pain.
You got me curious!
This looks like a start:

But then why is this a separate thing?

Anyway, there may be better brands. Do some digging first!
I thought, can't wait for all the jokes about smearing a house with yoghurt, only for that to be what the article was actually talking about 😒
