What type of glazing do I have?

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) !
