What your eyes see can fool you.
Because Orca and many other brands diffuses the light, a lot of the light goes straight to your eyes.
Thus we are thinking that it must reflect well.
But it is not true at all.
The best material is material that gives direct reflection.
Like a mirror.
So the best material to use would be a mirror.
Although it might not be the most practical.
What you can do is take a light meter and use it to measure different materials.
There was a Dutch grower who took this test very serious and did it in a semi-scientific way (so not relying on his eyes) and I will post some of his outcomes.
Mirror foil performed the best, so he called that 100%.
Second best was alu foil > 97%
mirror glass 3.2 mm > 93%
mirror glass 6 mm > 89%
Some radiator foils > 70 to 80 %
White paint > 63%
Anti detection foil > 60 - 62%
Diamond foil > 57%
White side of B&W foil > 54%
Orca foil > 53%
The best is to have it as straight and flat as possible.
So the angle on the incoming light will be the same as the angle of the outgoing light.
Some materials have other disadvantages such as cleaning-issues, and alu-foil for example will oxydate.
