Determining What Type Of Glazing You Have:
It's generally easy to tell the difference between single
and double pane glass. It can be difficult to determine the
difference between Standard Double Pane, Double Pane Low-E and
Solar Control Double Pane Low-E. If you have having trouble
making the exact determination, see if you can locate any
documentation on your windows or check for any etched in markings
around the corners of the glass units. If you are not able
to make a determination, our advice would be to use your best
educated guess (absolute confirmation may require a destructive
test) !
