In most cases, it is not. The r-value of a single pane windows is about 1. The r-value of 2-pane garage door windows is about 3.
This is not going to make a big difference in the garage temperature at your home in Greater Cincinnati or Northern Kentucky.
And the cost of 2-pane glass in a garage door is almost double that of single pane glass.
So for most homeowners, a single pane of glass for the windows in your garage door is the better choice.
