Google it. I always just called them louvered. They're great for letting cool air in, bad for keeping cold and wind out when they're closed. No experience with insulated windows. Whole house fan is great. And yes, louvered slats near the ceiling are for passive air or whole house fan if there is one. And they do stay open all the time (at least ours does) so again, bad for keeping heat in during the winter.
