Look closely at the right hand window now. Yup, this is my house as it appears from the outside, and you can clearly see that window is stuffed full of colorful insulators. I'd love to be able to put insulators in the other three mini-windowlets (the wing windows in this shot, and the bedroom window on the left in the last shot), but they would soon end up in pieces on the sidewalk below. So this is as good as it gets.
