Your issue is not the glass, yet. To meet or exceed ES guidlines
verified air infiltration tests should be good meaning you could have
a defect. I dont think you should feel air comming in on an Energy
Star window, get the test data from silverline and compare it to
others.

Which is what I said earlier -- I'm convinced the air infiltration is an
installation problem, not the window itself.

He said the air comes in the side tracks of the window that would not
be an installation issue although with his uneven heating and an 80%
furnace the builder cut corners.
