Aluminum Foil on Window Hit by Sun/Heat = Cooler Room Temperature (Heat Wave)

Be aware that shielding the sun radiation from behind the window may increase the chance of the glass cracking (thermal stress). The chance increases significantly with imperfect glass/install, cold/hot spots and a thinner glass/pane ( double/triple pane glass usually has thinner glass ).

Up to 5 degree Celsius lower depending on window/room size.

Good for you.

"From 1998-2017, more than 166 000 people died due to heatwaves, including more than 70 000 who died during the 2003 heatwave in Europe."

For a lot of people, "portable" AC is the only option. Most of them can't cool an extreme hot room.

Or put up aluminum foils. It's environmentally friendlier too.

If it wasn't for the fact that most homes aren't designed and built for them, shutters would be much more effective so this is 2nd best..

I was wondering why they called it a "shutter" when it doesn't shut.

real shutters in Italy

Because like many things in N.America (especially USA), things are just plain wrong and serve no practical purpose. I personally think decorative shutters are silly. Either install a proper functional one or none at all.

10% off is cold, 50% off is warm, 75% off is hot, but FREE IS RFD!

Purely vestigial and decorative in North America for the most part. With a gap between shutter and window, a nice little boundary layer is created which helps thermal insulation (summer and winter).

Shutters are de rigueur in older French houses but the new ones don't seem to have any. These are not just for insulation but for security as well.

In some countries, shutters can swing out from the bottom to provide more shade and ventilation.

Yes, nasty heat wave in BC, was 43C in my area yesterday and I had to do some dirty work in the house crawl space. I have 3 x 5000BTU air conditioners and all they can do is take the edge off the heat and humidity, need lots more BTUs of AC for these conditions. This heat wave has very little wind and temperature drop at night so the house walls and framing remain hot like 30 to 32C all night and that makes it easy for the sun to heat up the house the next day.

5,000 BTU isn't that much (I think x3 is "1 ton", maybe 1.5 ton?), and the way these are mounted (assuming window, or portable with hose outlets) is itself a source of heat ingress.

My house is well insulated so the heat pump could easily maintain 24C for the 66 hr period is was on (never let the house warm up inside). I guess if houses had light coloured roofs and light coloured walls, it'd help tremendously at least in the hot season.

A lot of new ones do, especially in cities. They’re not the traditional swing shutters, rather are roller shutters that integrate into the window.
