It’s the same if it has this silvery surface which reflects radiation. Also don’t expect miracles. If you park in the sun, the air inside will still be super hot. The actual advantage is that your dash, steering wheel and seats won’t be lava when you get in the car.
Ah sad… because I looked all around my Workplace. There is not one single parking spot in the shadow… So my car will still be burning… I was exited here for a second.
The other guy isn’t technically wrong. But I know from experience that while your car will be warm on the inside, using the shade will mean the difference between unbearably hot and warm.
Just park so that your car points mostly towards the sun so that the windshield has the most direct sunlight and put up the shade.
The reason it works is because the sun gives off IR radiation (in addition to visible light and UV). Glass traps heat when given by IR. The IR passes through the glass, hits the interior surface, then gets converted to physical heat. Which is then trapped by the physical barrier of the window. The cover reflects most of the IR back into the sky. So the car mostly warms up from heat absorbed by the ambient air temperature, instead of being blasted by direct sunlight.
Exactly right. I just meant that it definitely still will be uncomfortably warm when you get in at first, but overall hear will be lower. So definitely use it!
Preventing the interior from being hit by direct sunlight also has the huge advantage the once you let out the warm air, there are no superheated parts that continue to radiate heat for many more minutes, making the actual ride much more enjoyable as well.
You can use the same Windshield in winter and summer (I did many years). When it is used from outside, it helps even more against the temperature.
It is a bit more fun though, to use one with big eyes to be positioned inside and make your car look like from Cars movie.

We have the red version (strangely ours was much cheaper here in Germany than what I just found on Walmart website) in our little red Toyota and aside from keeping the car cooler it is looking really cute.
Is this any different to the thing I put outside my Windshield in winter? Or can I just use that?

I’m also from Germany :) You can see that from the Server I’m on. Tchncs.de
It is a small world in the Fediverse :)
yes you can use that, and to be most effective you also obviously put it outside
Thanks
