It's an interesting topic for a website like this. My family and I moved into a new house and we had special reflective windows installed, which made us feel so comfortable spending time at home and looking out at the garden (as if there were no window). They can also be ordered on the website https://www.tintfit.com/shop/reflective-window-film . We found out about this when we asked the seller about these windows.
