all the stickers of a store window? Our contractor dropped off to-be-installed windows with very little information on them - just a generic white sticker with factory codes. Can these be the low-e, argon windows we ordered? There are no Energystar stickers on them, like the windows in Lowes. The factory is right down the road in Durham (we're in Raleigh). Also, they had half-screens, unlike the full screens we ordered. How can we verify the order is correct? Thanks.
