LoE2 window glass test
I remember reading somewhere that you can tell if you have lowE2 glass and if its installed with the right side inside. This was some years ago. I know it said you use a flame to hold up near the glass and you will see 3 reflections with one a slightly different color.
I know I have loE glass and I get 4 reflections 2 groups of 2. and the 3rd reflection is slightly more orange from the inside but not the outside. Does anybody know the proper test and the proper results? Can you tell LoE from LoE2?
