No problems with what you say. Perhaps I could have mentioned that, even if the screen/tint heats up, it radiates half that energy outside the vehicle. I was just thinking about the fact that black bodies maximally absorb and radiate electromagnetic radiation (visible and infra red), and that a lighter color on the outside surface would minimize heat transfer into the vehicle, like the silverized ones on my old Volvo screens. (These were black on the inside surface, of course.)Even if it didn't help the heat at all, it also would save the car's interior from the sun. But, it may reflect heat better than it reflects visible light. And it does reflect visible light, even though it looks black at first. Depending on how the light hits it, it is not really reflective, but doesn't look like black felt either. I guess my point is to not assume that it doesn't help with heat. Since the days are only just starting to get hot, I don't have a good feel for it yet, but I think it is helping.
But it does help with the sun-in-the-eyes effect for kids in the backseat.
Since you brought up the "old physicist" thing, I'll have to bring you up to date. The company I work for has developed several IR reflective pigments, including a black. You can now have a black interior that will not heat the car anymore than a tan interior. Some of this years models are starting to implement these new pigments.No problems with what you say.

In any case, it's not a big deal, especially if dark screens do the required job and satisfy the customer. In actuality, I'd prefer to have pull-down shades for all windows, including the windshield.
Jus' can't help thinking like an old physicist.
Hey, that's neat. I would think black cars will really benefit. Thanks for the info..... The company I work for has developed several IR reflective pigments, including a black.

Or to put it in another application, you will be able to paint your vinyl siding a much darker color without fear of it warping out of shape due to heat absoprtion.
FYI, the first part number is WRONG. I ordered the part mentioned above and it is for the 2007 variant and does not line up correctly. Great.Here you go:
1K9064363 - 2 shade set for backseat windows
1K9-064-365-A - 3 shade set for luggage compartment (rear window and 2 small side windows)
Order from dealer, input that into google or go to the parts suppliers and order. I've used keffervwparts.com for a decent discount.
I got the ones for the Golf and my little niece loves to ride with me just because she's not getting a faceful of sun in her carseat.
Congratulations and good luck with the little one.
