I shall disagree but I am afraid my source has passed on. An expat tenant put up a high-quality shade tarp over the dirty kitchen in the back of a unit he was renting in 2010. In 2014 I moved into that unit for a year and the tarp was still in great condition. I asked the previous tenant where he got that and who installed it and he said he would tell me if I bought him lunch. I kept postponing and never did find out. The tarp is still up and doing well but it outlived the expat who bought it, sadly to say he passed away earlier this year. Point is the sun did not harm it. The trick was that it was installed so extremely tight that it did not budge in the wind. That was possible because the tarp was high quality. It is the constant stretching and whiplash from being blown around by the wind that seems to destroy good tarps here. At least that is how it seems to me.
That's what I was thinking, the material went like paper. Had a quote 5k to recover the framework. they said it was long-lasting, hmmm
