Hi. I am converting my home in Alaska to a Corporate Retreat. Inside the retreat I will be having a ”Tropical Room” that is 40′ X 32′ and cathedral ceiling. It has a large swimming pool a Jacuzzi, steam room, and three water fountains, I am worried about the windows. My windows will go from floor to almost to the top of the eve on the roof, to allow visitors within the tropical room to view the Northern Lights. HOW can I prevent foggy windows, or ice buildup when the ”Trop Room” is 80 wi
