Just another option if you have a skylight and don't care for it. There is batten, reflectix and luan between outside and inside. Outside is coated thick. I had planned to remove the outer dome completely, but got lazy and left it for now. I'm of the opinion mentioned earlier. If I want natural light, I go outside, if I want light inside, I turn the light on. But, it's an option and some like them, and that's all good.
