Xringer,
The title of your thread is SunTex Solar Screen...
Did you know that you can get this stuff from garden supply stores at a much lower cost? They sell it as shade cloth and is comes in various quantities, various percentages of light blocking, and even various colors (even basic black).
Here's a link to one source, it's straw colored and 90% block.
It comes out to 37 cents per square foot.
How does that compare to the SunTek stuff?
Here's 70% black for 33 cents per S.F.
Here's Black 40% for 12 cents per S.F.
Here's one that is probably 60% for 1.1 cents per S.F. (sounds like error, but there is the ad)
