I've heard about scoring the glass on only one side and scoring it on
both sides as the preferred way to cut/break glass. I've done it both
ways. Anyone got any real insight into this matter????

H. R.(Bob) Hofmann

score it on one side. break apart by pulling down on each side of the
cut
with the cut on the top surface, or break on a sharp edged tabletop if
the
piece of glass is large and the part you're cutting off is not small.

Any comments on scoring 1 side vs both sides before breaking??

I should add that this particular piece of glass I am going to cut is
double thickness from an old storm door. I know that the glass is NOT
tempered.

i cut up to 1.5" glass usually. the score breaks the surface tension. you
bend away from the score, causing a compression of the bottom surface. if
you scored it, it would make no difference, and would probably cause your
cut to wander since they won't line up exactly anyway.

how do you know it's not tempered? lack of a label doesn't guarantee that.
if it's a door, there's better than an even chance that it is tempered. i'd
wear eye protection before scoring it, if i were you.
