warranty question: double-pane windows with moisture between the panes

First, I have my actual written warranty for the double-paned windows
on my house; and the windows are still within the period that the
window manufacturer will 100% replace any windows with seal failures.
I've owned the windows for less than 5 years. These are likely
less-expensive double-paned windows that the builder installed.

I want to be reasonable with the manufacturer, and so here is what I've
done so far.

First, I cleaned all of the windows on my house, and inspected them for
different grades of moisture between the panes.

1 - visible small droplets / fog in the window - no ambiquity of seal
failure

2 - mild streaks of fog with a few small spots of heavier moisture

3 - mild streaks of fog visible between the panes, no visible droplets

4 - few streaks of fog visible

5 - window looks fine

Now, I went around my home and graded each window.

Question: For the above grades, what do you think is reasonsable to
expect the window manufacturer to replace under warranty due to seal
failures?

I'm thinking of definitely pushing for all of the 1s and 2s. I'm not
as sure about pushing for the 3s and 4s.

Thanks.

Dia duit

grab the warranty coverage now on 1-2-3-4's and hope your 5's dont fail
soon after warranty expires.

Your warranty will state the condition . Pellas 20yr warranty states "a
permanent material obstruction of vision'" in the warranty. I see it as
any obstruction-moisture, indicates seal failure. So 1-4, no matter how
small the issue. If many are defective, they all may soon be bad.

When the seal breaks, the argon gas that is normally sandwiched in between
the panes will escape rendering the insulation value to nearly nothing.

Well, it might become an R2 window.

Over 20 yrs 10% of the argon is expected to leak out resulting in only a
few % reduction in R value.

What's the written guarantee say?

Which, it bears mention, is only slightly worse than the insulation
value of argon gas! Gas is not a terribly good insulator.

The biggest problem with seal breakage is the appearance of the
moisture, and as another poster said, any appearance of moisture is
too much.

It's not bad. Neither is air.

shows a low-e and argon combination raises the US R-value of double glass
by about 1, from 2.04 to 2.86. Neither are "nearly nothing," altho they
are small, compared to an R30 wall.
