I don't know if this is generally known but I wasn't aware of it until a Velux repairer (kindly) told me that some of these windows manufactured around 2001, see code below are replaced FOC, its a batch with code OOUE. I don't know if you contact them even if you have no cracks if they still replace them.
I returned from holidays to find a large crack in one of two attic windows, both window modules were replaced, what a service after 23 years. Apparently a vacuum forms between the two glasses and the inner one then can crack/shatter, the installer told me the glass thickness is now 8mm vs 4mm.
