I used this to cover my chicken coop and run essentially creating a greenhouse for the chickens during the cold upstate NY winters. Held up great through the entire winter including heavy winds. I took it down in the spring and folded it up and left it in a pile behind the coop. I purchased new plastic for this winter but last years plastic is still as good as new so I simply reused last years and stowed the extra. Very strong and withstands stretching. I had tree branches fall onto it and no punctures. I'm going to build a greenhouse with the new stuff before the snow hits so I'm ready come spring.
