Side note:
When using ‘Kelvin’ as the scale, the degree symbol ° and/or the word ‘degree’ is omitted..................
The materials used, see key words, are cheap common materials....................
You may not believe me but I got an A in thermo.
Now there’s and idea!
Also make it easier to wash the window!...............
I bought something like this at Home Depot 5 or 6 years ago. It’s still on sale there. It’s a retrofit product that you put on your west facing windows like a decal. You clean the window inside very very thoroughly, then spray a solution on the window and slide the film into place then you squeegee the moisture out the sides, wipe smooth and trim with a razor knife.
My house faces due west and in the summer days from 4 till 8 the sun just beats the front of the house. My upstairs has 3 bedroom windows facing west and the upstairs was always 3 degrees hotter up there. This film dropped my upstairs temp by 3 degrees almost instantly. The drawback is it appears the windows have sunglasses on them during the day as the film acts as a mirror. You can’t see in during day but you can see in at night.
this is a product I could support.
That’ll be a must for my motorhome for sure. The heat from the sun coming through that huge windshield despite running the generator with the 2 rooftop a/c’s still doesn’t cool enough

Nah.... central_va and ShadowAce precede the 13th CGPM.
Clever idea.
Double edged sword. Heat blocking windows are nice for hot summer days. But they also block the heat on cold days when that heat is beneficial. You will actually notice it in a house where the windows were replaced. The heating system has to run a lot more. The house does not heat up in the daytime just from the heat of the sun. What would great if they could design a window that can switch heat blocking characteristics on and off depending on need.
This seems to be an improvement on something that high-end window tint films have been doing for a while now. They use super thin layers of material with precise spacing that causes destructive interference in the incoming light. By fine tuning the spacing they can block UV and IR wavelengths while still passing visible light — so the material looks clear to our eyes.
One of these films is made by 3M called Crystalline:

Lets you block out unwanted light without having to use limousine dark tint.

OK, but can it block Canadians??
As one FReeper put it: Turn the window around!..................
Shutters cheap and easy to use worked for years.
Red light therapy is useful for reducing inflammation by suppressing TLR4. Sunlight on bare skin offers similar benefits when possible. Not an option in Winter temperatures.
You should get the Zot for posting that pic.
Lol!
Sounds like the formula for transparent aluminum.
:)
Something like this came out in the 1990s.
The label read something like, “E-lighting”
