Number of mushroom head pins EG / OG

Thank you for your opinions.

Yes. 2, no matter how big the window is. I find that, at least for the ground floor, quite little... Expanding to 5 mushroom heads costs about €35 plus tax per window. I do not have any other prices or prices for even more mushroom heads.

2 pieces are nothing for a normally sized window. As already mentioned, it is sufficient for small WC windows.

Here you can see how many are required at a minimum for the different resistance classes:

Exactly. We decided on RC2. We also wanted to have a film installed between the windows so they can't just be thrown in, but that would have exceeded our budget.

On the ground floor and at the balcony doors on the upper floor, we chose RC2 (this was the window installer's suggestion). But it doesn't help if, like me, you often go out through the terrace door in the morning and then leave it unlocked throughout the day :D

A burglary-resistant window has a test certificate (RC2 to RC6 possible). The dealer must also hand this over to you. Additionally, I would ask to see the test report (does not have to be handed over), which then states the number of locks and also the glass. If he cannot provide this, he has no knowledge of security windows.

With RC2 there is a film in the window, right? The outer pane consists of two 4.5mm thick sheets of glass, with a film in between.

Then you have RC2N... there the glass is not reinforced, but that doesn’t actually make much difference in price...
