The more you use the space blankets, the quieter they get. I still have the same one I bought when I got my hammock. You can also ball it up and smash it over and over again to quickly break it in. Mine doesn't make any more noise than the nylon on my sleeping bag. I bought some reflectix and tried it with the OCF pad. It seemed negligible to me that it was any warmer. And it takes up more space.
