Should my new double glazing windows bend???

thats a big unit, I take it you mean c.m. not m.m. Basically a piece of glass that size will flex and theres not a lot you can do about it. It should not be made from 4mm glass though and if my memory serves me correct is only just within the tolerances for a 6mm unit.

Yeah i measured in cm.

So, i have every right to demand that the glass be replaced with the correct 6mm?

This will give you a guide to dimensions. This is from a company and so you will have to google the exact regulations.
