feel your walls in the winter. when they are cold do you really think a little more glass will make a big difference?

It's the dead air space that makes the difference, not the layer of glass.
Biggest benefit to us was noise reduction. We tailgate in noisy parking lots and it made a noticeable difference.

A 50-70.2% increase is a great improvement. The dead air space between the glass is what make the improvement. This is the same type of glass that is used in our homes. Most windows with double pane insulated glass have a 3/8" air space and a R value of 2.8. Check out a good window company like Andersen Windows and see what their R is.

A quick Google search indicated R values for a single pane of glass anywhere from 0.85 to 1, so using the highest R value (1) and the lowest improvement (an increase of 1 to an R value of 2) leads to a 50% improvement in thermal transmission at the conservative end.
If I wanted to inflate it, say the single pane R value is 0.85 and the improvement for the dual pane is 2, to an R value of 2.85. The reduction in thermal transmission would be 70.2% at the optimistic end.
Either way, it's not insignificant, AFAIC.
