I had a windshield replaced last summer. It makes no unusual noises, doesn't leak water or air, and, with the exception of two small gaps in the outside trim, looks as good as the original.
A properly installed replacement windshield should not leak or make noise in any way.
I suggest you take the vehicle to a different windshield replacement company. If they haven't gotten it right in three tries they're not going to.
I don't think I'd let anyone do it outside in cold weather. Take the van to a shop, leave it there, and let them install the windshield in a controlled environment.
