I don’t know the make but I will look.

If they need replacement my concern is around the windows as we have stucco. I was here everyday when the house was built so I know it was done right.

With modern double pane windows, you can have the IGU replaced but leave the frames in place. That wouldn't require removal of any wall or trim inside or outside.

If your IGU had failed, I think you'd know.
