ᐅ Window tolerances: frame dimensions and squareness

Hello everyone,

can someone tell me if there is a general tolerance for windows? Not the rough opening.

Specifically, I am concerned about squareness. I have a plastic lift-and-slide door where the vertical frame is not at a right angle. When the door is open, this is quite noticeable. At the bottom, the glass is hidden behind the fixed part, and at the top, there is almost 3 cm (1.2 inches) of visible gap.

Is this considered a defect? Or do I have to accept it?

Thank you very much and best regards

Could you take a photo?

Maybe it’s “only” 2 cm (0.8 inches), but that’s still too much?

Yes, it looks awkward, but if everything seals properly, it is probably a minor defect.
I mean, 2cm (1 inch) over 2m (6.5 feet) – and it's likely even higher, right? – is only about a 1% deviation... Annoying, but I don’t think you can achieve much with it...

Is the window crooked or is it the frame?

2 or 3 cm (about 1 inch) with the window closed means it will never be airtight, right?

I also think it is so crooked that it might be intentional: is the reveal so uneven that the window fitter or measurer deliberately passed it on this way, preferring to fit the frame directly to the reveal rather than cover the gap with a noticeable wedge-shaped trim?
