It sounds interesting. I wonder about the lifespan. "remarkably durable with an estimated lifespan of 60 years" i would think it does not just break. Of course I expect they have not been studying it for 60 years. Does it degrade steadily or quickly near the end of life. Also, I would like to install them tomorrow so if you are working on this hurry up:) (and make it easily affordable please). I m also watching advances with radiative coatings.(https://www.sciencedirect.com/science/article/pii/S2949821X23000029 https://www.sciencedirect.com/science/article/pii/S2949821X2...).
