Hey 215, from the looks of it you are ducting to cool your room? Or just for your hoods? I use the insulated duct as well, 8", but only on my hoods. So long as everything is insulated the entire way through I don't see condensate. In other words, I come in, go through the hoods and go right back outside with it. So long as the air never has time to sit or cool anything down I won't see condensate. It is only when you have that cooling effect on warm exposed parts that you begin to form condensate. If you can insulated everything that comes in contact with the cool air you shouldn't have a problem there.
I hope that is what you are asking about.
