Is safety glass necessary or not?

I can certainly find you a few more articles where the opposite is stated.

But not with blanket coercion. At most, window installers write like that to sell.

Maybe. You can also reject a RAL installation of the windows and have them installed the classic way with foam, because RAL installation is not mandatory either :) but an accepted technical standard just like the DIN. Good night :cool:

If safety and cut protection for your children come first, invest the extra money. If you consider the risk to be marginal, there are ways around it. I would choose the safety glass because I witnessed an accident involving an inward-opening door that broke with a sharp edge hitting someone's back. On the other hand, I have no problem taking children on the old tractor, which is objectively much more dangerous. The assessment is simply subjective.
