I have recently noticed that on some on my windows that the double glazing is no longer sitting flush in the frame.

Hopefully this can be seen from the pics. You can see that the frame is bulging in the middle, and has shifted in the corners.

There are no visible cracks in the walls at all, and the only thing that I can see that is wrong is with the metal frame of the dbl glazing

I at at a loss as to why this is happening.

Is anybody able to say what is going on? and if I have a major problem.

Thanks

Hi darrenguy
The only possible reason I can suggest is that the wrong size setting blocks have been used and they are in the wrong position. You will have to remove the glazing beads and take out the DGU to check this.
