I have a newly built house and was told the windows are E windows (with
Argon gas). I know very little about these types of windows, but recently
found out that the window company had to come and replace one of the windows
to make it an E window because of a backlog.
My question is: How do I know it is an E window? Is there an icon or
something that I can check each window with?
Thanks for all answers.
By the way, I asked the installer when he came over, and he gave a very
vague answer. He showed me these two holes near the bottom of the frame and
said he 'thought' that this means it is an E window but basically said he
wasn't sure. I also checked the light colored icon and inf. on the window,
but it only said 'tempered glass' and some numbers that mean nothing to me.
