Query: Not very strong

It didn't take too long to install. But the very next day, one corner of the plastic sheet came down. And it's not even windy right now. I hate to think how this will hold up when a cold, windy day comes along. I'm going to try a different brand of double-sided tape to see if the plastic will stick to it. But I shouldn't have to do that.
