The reason is all vinyls are rated by hours outdoors. If you only count daylight hours, normally 1500 hrs outdoors is pretty standard which amounts to about 100 days. Makes it seem kind of silly to put vinyl on anything that’s going to be outdoors.
If it is exposed to temperature extremes and or UV, vinyl will always crack and fall apart eventually. That’s why Sunbrella ™ was invented. It has been the gold standard in outdoor fabric for more than forty five years.
One of the great advantages of breathable fabric is that it does not trap moisture in like vinyl where it can grow mildew. If rigid foam spa covers smell like mildew, the vinyl on the outside is one of the reasons why.
Sunbrella ™ doesn’t crack in cold like vinyl, or fade like canvas. If you live near a marina every boat top you see out there in a bright color is Sunbrella ™. Anything else would fade out quickly, even the paint on the boat will fade before the Sunbrella ™ will.
Years ago a neighbor came to me and wanted me to repair his sail cover. His sail cover had been on his sail boat for twelve years, through all the weather the northwest pacific coast could through at it. For those of you who don’t know sailing, the typical sail material needs to be protected from exposure when not in use so it is bundled and covered with a sail cover. The sail cover is the shield that covers the expensive sail from damage.
My neighbors sail cover was made from Sea Grass Green Sunbrella ™ which is a bold, fairly bright green. I explained to him that if I patched the cover with new material it would look terrible because new bright material would stick out like a sore thumb on the faded older material. I laid a piece of new material on his old cover to prove my point.
To my astonishment the only difference between the two was his was a little dirty. Once it was cleaned and patched, there was no difference between the new fabric and the old even after constant exposure for twelve years.
