I would put mylar sheets on my windows instead, although the best is of course to have shutters The traditional shutters from south east France are great to block the sun but still allow light https://volets-thiebaut.com/modules/boixmultiblocs/images/7a...

Using CaCO3 which is calcium carbonate, like the article.

An acquaintance in London painted his windows with Yogurt. Based on this advice https://www.architectsjournal.co.uk/news/paint-your-windows-...

He said that it helped.

Anything But A Heat Pump™

Have you been to Paris? Go on google earth and poke around. Theres no place to put the condenser. Most people rent so even if there was they can’t drill holes for the lines and even if they could, most buildings are historic so they can’t. Central AC/heatpumps on some rooftops could work.

If you live in a historical rental flat you often can't install AC.

Also we do tend to consider the environment here. All the heat kept out doesn't have to be pumped.
