I saw that shade cloth stuff and wondered how well it might work as a collector element.

After looking at the close up pictures in this link EasyShade Sunblock Black 40% Shade Cloth UV Resistant 6ft x 50 ft: Patio, Lawn & Garden

It seems like horizontal strings with floppy thin flat strips of reflective plastic, connecting the strings.
It seems like air flow might be a lot higher than my 80% screen.
Which isn't idea for the collector design I'm thinking of using.

It might work, if it's not too reflective and can stand up to the temperatures inside a sealed collector box.

Gary didn't like the out-gassing he got with the FG screen..

He thinks it might have been a film or coating & not the screen itself.
He's interested in testing the Suntex screen. (per his Email).

In one of the reviews of the Suntex 80%, the reviewer said he had switched
to using the 90% screen and found it was thinner and easier to work with.
That sounds real good to me. Price isn't too much of a problem,
since I'm not going to be building more than a single 4x8 footer.
That is, if I can sell the idea of a front-yard install location..
Which may not be possible. Unless the winter drags on until late June.

My hobby is installing & trying to repair mini-splits
EPA 608 Type 1 Technician Certification ~ 5 lbs or less..
