Weighing different options in the single-family house

Because the police are currently putting up posters everywhere here. Mechanical burglary protection RC2 is explicitly recommended. Not 1, not N, nothing else. RC2.

Because the police are currently putting up posters everywhere here. RC2 is explicitly recommended as mechanical break-in protection. Not 1, not N, not anything else. RC2.

Very difficult decision regarding the security class for the windows. If I understand correctly, RC2 is useless to me if the weak point is the glass, which can be smashed within seconds. So you would have to combine an RC2 window with appropriate security glass. Does anyone have an idea what additional costs to expect between RC1 and RC2 (with security glass)? Perhaps the amount would be better invested in an appropriate alarm system with fog system or something similar?

One more question that came up after reviewing the offers from the GU. I am completely lost here...
Regarding the meter cabinet, the following two options are offered:

(1) Standard (included in the price)

What do you want to connect?
Wallbox?
Sauna?
Instant water heater?
Other major consumers?

Does anyone have an idea of the additional costs to be expected between RC1 and RC2 (with safety glass)?

In material procurement about 1/3. Plus a proper RC2 installation. I would guess, for the general contractor, probably a 50% (+x) surcharge. Considering that even the police say that only a very small proportion of break-ins are due to broken windows, that is already a surcharge one has to think about or one meets halfway on security.

Another question that came up after reviewing the offers from the GU. I’m completely lost here...

TAB technical execution specifications, EVU energy supply company. But are you really already at the stage of being able to compare GU offers? (how is my answer from five days ago at 11:01, is it lying dormant in the spam folder?)
