I'm looking at small greenhouse application in hot/dry desert summer, small enough
that if glazing or film is a little exotic/pricey, but really does the job, is acceptable.

That it also diffuses incoming light would be a plus, too.

Water for evaporation cooling and electricity for pumps and fans scarce, and just
shading is always last resort if things overheating, but prefer not to, in trying
to maximize sunlight, by seeing what can better reflect IR before it gets inside.

Appreciate any suggestions or links to promising new anti-IR glazing/film prospects.

Thank you!!
