To my knowledge, this subsidy only applies to renovations and not to new constructions.RC classes only define the time that the window/door has to withstand with a certain tool. How the manufacturer achieves this is up to them. Our windows with RC2 do not come with lockable handles.
What is important is that you receive a proper certificate afterwards, showing your window/door type and the resistance class. Some manufacturers have their own resistance classes, which are then similar to RC2; you just have to trust that.
I consider €75 ambitious for RC2. For doors, RC2 costs between €300 and €600, depending on whether glass is included or not.
Currently, there are KfW subsidies for RC2. You actually get almost as much as the surcharge costs.
