I just received this tarp (white) and installed it as a sun-reflecting cover over my dog kennel (which I'm using as a catio). The kennel came with a black/silver peaked roof covering. Even with the silver side out, the catio gets too warm inside in bright sun. I bought this tarp to add reflect the sun and keep it cooler inside. Works like a charm. This tarp is heavier than the one that came with the kennel kit, so it will likely keep more water out as well (although I won't have cats in it when it rains). The tarp seems like a quality product and the grommets are firmly attached - none of them were loose when I was attaching it with the bungee bands. I can't rate the durability or weather-proof qualities, since I just installed it on a nice sunny day yesterday. I expect it will be fine. Thanks!
