Hi,

We had a few double glass panes replaced in our existing windows that had become foggy (no change made to the white vinyl frames). After completion, in some, there is a small bit of black showing in the inner edge of the window from the sealed border of the new glass. Is this just a normal thing? (Or is it a defect in the sealed glass, or in the alignment when the glass unit was placed into the frame?)

I do see some of the old glass in our existing windows has the same thing -- it's just less noticeable since the sealed border there is silver/aluminum instead of black.

Thanks! (this is enlarged; it's not as big as it looks in the photo, its a couple mm only)

 

Sloppy job on making the insulating glass unit. The sealant spread past the aluminum spacer and possibly the glass size was too small. Post a photo showing all 4 sides.

 

It looks like the glass panel was not installed square in the frame, probably because it's undersized a bit. The strips that hold the glass in place can be popped back out and the glass realigned. It might be good to install some shims or use a couple blobs of silicone to help hold it in position.

 

When they measured for the IGU they may have rounded down the dim or it was made to a smaller dim, or there simply was some excess room inside the frame.

It will still function as normal it was just installed a little crocked.

 

Thanks. Here are images of all four sides on a couple of windows.
Seemed to me the glass pack was not set in straight, but I don't know a lot about windows.
Could this just be aligned?
Is this just cosmetic or could it cause structural issues?

 

Without removing the stops, it's hard to tell exactly what happened. The IGU may be too small and therefore you can see the inside edge of the aluminum spacer. Maybe they should have used what we call, "narrow site-line" spacers to make the IGU. They are narrow on the face which will allow the black sealant to be hidden by the stops. Other than the first photo, they are not that bad. How did the original IGU look like?

 

It's cosmetic!, the IGU jus fits within the frame.

Agree, from your recent posters I don't even see anything that looks obvious!

 

Normal stuff.
