I have some glass skylight windows that add too much heat in summer (but are wonderful in all other seasons). Previously I covered them with aluminized bubble wrap insulation, which is a pain to install because of the wind that rips along our roof.
I know weightlifters have bags of chalk, for "gription." Where can I get this stuff cheap?

"Why French people are painting chalk on their windows in the heat"
"As record-breaking heat sweeps over France, some shops are running out of a simple, cheap and unexpected product – crushed chalk.
Known as Blanc de Meudon, or Meudon whiting, it is normally used to make paints or as a cleaning product. But faced with punishing temperatures, there are reports that ingenious people have been using the chalky material as a home remedy against the heat, covering windows in schools and private homes.
Mixed with water, then painted on glass, the result is a milky, whitish coating that lets in some light but reflects the heat. And a growing body of research suggests that there may be some solid science behind the DIY cooling hack."

So far all I have come up with is pallets joined at the edges in zigzag. And long “berms” of stacked corkwood. And T posts pounded in and upright poles and branches sort of woven in to parallel horizontal wires attached to the T posts. I guess a giant brush heap might work.
