I have done some searching and reading here and haven't come across an answer...
So my question is... what kind of wind and sandstorm protection does aluminet 70% provide?
Ready to be beaten with my own post...

No need to be beaten at all. (Unless you like it). And you dont need to cowtow to anyone. Its a valid question. Of course the usual suspects and their insecure snarks will tell you otherwise because... Welll... I will let them explain their behavior. In the meantime lets talk about your question.
Aluminet is indeed a net. Of an aluminum-foil-like-thingie construction. Its kind of a wierd woven creature that blocks (reflects) about 70% of light and passes the rest. It was developed for use in agricultural situations where seedlings needed light and air but not 100% light and air. A LOT of this gets used in the Phoenix, AZ region where open greenhouse growers cultivate 1000's of acres of early-start plants. This is what it was designed for.
Others have posted a picture of the product so please refer to that. It wont stop a sandstorm. At all. But it will knock down (get this) about 70% of the bigger grains. But the powder will go right on through. On the playa this means you will be cool, and only mildly sunburned, and very dusty. It does not create "black shade".
Note that playa dust is a mixture of both sand and powder and everything in between. As the wind speed goes up, the particle size increases too. During the really big blows you can collect 40-grit sand 20 feet above the playa floor at 4 and K. Pretty impressive!
Back to your question: will it stop a sandstorm? No. But it will slow the wind down a bit and allow some of the suspended coarse matter to drop out. And it will catch monkey huts, sparkleponies, and the occasional FlyCycle. In other words its better than nothing but a far cry from dust-proof.
So there you have it. Aluminet isnt ideal for dust-storm protection. But its good stuff otherwise!
Oh. BTW Welcome!
