Energy Saving Window Covers?
(OP)
Our plant has excellent exposure to the sun throughout the day. With all the windows we have, in the winter time this is good but in the summer it is bad.
Anyone heard of a material that will let the sun's radiation through from one face and then stop the radiation by flipping it to the other face?
Anotherwords, in the summer it will block the sun's radiation and in the winter you would turn to the other side and it will let it though.
Any "magic" materials out there?
Thanks

Not inexpensive, but, compared to the cost of oil it's a bargain.

There are film materials that have integral louvers, similar to the privacy screens for laptops. The idea is that summer sun is higher in the sky and rays are blocked by the louvers. Winter sun is lower, and more of it passes through the louvers.

I would like to know, though, if there is something that will allow us to have our cake and eat it too.
That is the covering rejects sun-generated heat in the summer and lets it through in the winter. The only way I can see this happening is that the material has two sides and one side rejects while the other accepts the energy.
This is why I refered to it as "magic".
I suspect that, if such a material exists, then it would be rather revolutionary.

The reason you see more summertime rejection capabilities is the fact that cooling cost a lot more than heating.
