Are you kidding? All the low-e glass in windows now has multi layered coatings. They are code required now. Every new window has coatings. I spec out cardinal 366 low-e glass all the time. All the window manufacturers use just a few glass suppliers.

And these coatings save money and save energy. That’s why they use them.
