Does a window with PPG Low-E glass appear any different from a regular window?
There is a slight difference in appearance, but this difference is extremely difficult to see between windows in different parts of a home or building. If you install a lite of low-e glass directly next to a lite of clear glass, you will most likely notice a slight difference. If you install all low-e glass on a particular building, it is a low probability that the typical observer will know that it is any different than clear glass.
