Would it be of benefit to install window film on Low-E glass?

Low-E windows only block a small percentage of UV and virtually no heat and glare reduction. Low-E windows in Colorado are designed to retain and not to reject heat. In the summer the windows will intensify the heat in the house. Installing window film on Low-E glass is an incredible addition to the window and the properties they already contain. The combination of the two will not only provide over 99.9% UV blockage but an incredible savings in energy cost.
