Did you have RC2 windows installed?

The link is good. Why didn't you post it directly - it's from a public/government source without advertising.

It doesn't matter - in the iPad era, people only enter search terms anyway.

Hi,
we will also install the RC2N version. So only the increased number of mushroom head fittings. Our general contractor charged quite a bit for that: it was about €140 for a normal window sash and about €180 for a floor-to-ceiling sash (=terrace door).

When I searched on various vendor websites online, the price difference for otherwise identical windows was usually more in the range of €40-80. But that's just the fate when you build with a general contractor...

Best regards,

Andreas

828 € for 11 wings - lockable olives and mushroom cams => ~75 € per wing

Who takes RC2. With 14 elements just under 2,000 EUR surcharge.
