simple explanation of the difference 80% vs 90%  

I will do just that

@danielchamorro1288 the best source, and a full turnkey jib at that, is Shields Up Solar Screen Osvaldo 832-609-6716 With a minimum of only 8, he will do all the work for you

From personal experience, the 80 allows the air to flow without restriction. The 90, however, very little air flow unless you add a fan to the window. As far as heat, 1-2° difference.

thanks a lot for the details!!! 👍

Thank you. What about the difference between 90 and 95?

@tashalicious79 my opinion..light. 90 is a dark tight material, 95 even more. 95 is most effective as a rolldown shade but some use it to make fixed Solar Screens. Very dark and somewhat difficult to see through
