AFRL assessed the effects of an after-market coating that could possibly be applied to FAA air traffic control tower ATCT windows intended to improve visibility out of the towers. Based on the results of the study, there is no reason to believe the coating would degrade vision through the glass for recently coated glass for the room temperature and humidity under which the samples were measured. However, the coating can degrade the view with haze at certain times of the day based on the angle of the sun. With the unexpected result that the coated side of the glazing increased observed haze effects, it is recommended that this phenomenon be investigated further. Additionally, the coating effects the distribution of water droplets from rain in such a way that one would expect improved visibility through the coated windows.
