ᐅ Lockable Windows / Emergency Escape Route

Hello,
we would like to have lockable windows throughout our new house. Our home builder’s planner has now told us that at least one window must have a standard, non-lockable handle for escape route reasons. Is that really the case? Where is this regulation stated?

Best regards,
Sabine

I always find it quite absurd. A lockable window is not considered fall protection because it isn’t locked, but it’s also not accepted as an emergency exit because it is locked...

Somehow, a window seems to be the worst element you can plan for.

Unfortunately, I can’t offer much more help than to say that a handle set with a lock in white is easily available for about 20 euros and can be replaced on standard windows in three minutes.

Maybe something like an emergency hammer on the wall, like on buses, or an axe in the hallway could help?

Or is the idea simply more about theft prevention, meaning that no one can get in from the outside? Because I don’t fully understand the purpose—should this be the case everywhere or only on the ground floor?

Of course, the lockable window handle serves as burglary protection. I would have liked to know if this is actually stated somewhere. It also means extra work to replace the handle afterward, and it should naturally be the same type.

Best regards,
Sabine

This is really how it is with the second emergency exit... just try googling it. But as already mentioned, simply equip one door with a standard handle and you can change it yourself after construction. I keep all the keys handy, but out of sight near the windows.

We have a children's room facing the balcony. The handle remains locked when no adult is present.
