Have always had white colored cars to help keep the interior cooler (although the portion of the interior heating due to the greenhouse effect through the windows is unaffected by car color). Recently whitewashed the roof on my house, which resulted in a noticeable reduction in A/C and attic fan operation running and making it possible to work on the roof in the middle of the day without getting a hot foot or burning up from all the heat radiating up from the shingles. Another advantage of having a white surface is it reduces the surface temperature change from day to night, which should increase the life of the paint or roofing material since it is not being as thermally stressed.

i have been thinking about using this on my rear windows to cancel the greenhouse effect.



this would be really cool

Yeah, my wife loves silver, so that plus the pizza pans would make silver my second choice. I've had this same conversation with my nephew. He finished his industrial design degree last year and his goal is to design supercars someday. He likes white because he can *see* the lines of the car better. However, he was mostly comparing white to black.

I should do the same. Here are some examples of "perforation density" :

CLEAR FOCUS Manufacturer of one way vision products, perforated vinyl, see through window graphics

Here's a monster roll for sale :

Roll of Intermediate Window Perforated Vinyl (one way vision) 6.3mil 38.5"X164'@ 00884962282878 | eBay

We should be able to buy some from a sign shop.

So... for purposes of automotive roof painting, now that I've been reminded to do it and have put a bit more thought into it -

What's the thought on a bright silver flake type paint color vs. white paint? (my car's dark "graphite metallic" so silver flake would look better )

...just about everything NASA puts up into space is WHITE for a reason, unless it's gold for reflectivity!

In addition to a reduced daily thermal cycling, another advantage of white is that it is reflecting all of the (visible) wavelengths of light, thus avoiding the longevity problems seen with red and black paint, which are absorbing the shorter, more energetic wavelengths (blue through UV) of light and eventually being degraded by their energies. Ever notice how the red on road signs is very quick to fade with extended exposure to sunlight compared with blue and white.

I was told by a plastic welder who manufactures custom items for commercial and marine use that the black PVC and polyethylene last outdoors in the sun and that the white PVC & poly deteriorated quickly by the penetration of the sunlight threw the white color damaging the plastic,
causing it to be brittle and break easily.
I wonder if the white paints condition, not the color, is more subjected to sunlight damage by its light passing white pigment.

It dawned on me that NASA makes everything white so they can find it again !
or
could be "we never get to "SEE" the black stealth stuff"
