The topic of windows is still on our minds.
The existing windows are 22 years old, double-glazed, and there are no anti-burglary measures in place. The house has a lot of windows, so retrofitting security features would be quite expensive.
Because of this, we are now quite unsure whether installing new windows might make more sense in terms of cost-benefit, heat loss, insulation, and overall value enhancement of the house.
All the windows have a U-value of 1.3. This refers to the value related to the entire window surface.
We know there are windows with a U-value of 0.6. Can it be assumed that this would roughly halve the heat loss? We have two children, so we also heat bathrooms, children’s rooms, etc. The house has a lot of windows, and we would have the costs for upgrading locking mechanisms anyway.
Or are new windows, with values approaching Passive House standards, so expensive that they won’t pay off within the next 20 years? Is this energy-saving aspect overrated?
There are 20 total window sashes... three of them are floor-to-ceiling windows. For at least 11 sashes, we would retrofit multipoint locks, and we received a quote that amounts to nearly 300 euros per window. So the retrofitting would cost about 3500 euros, but the windows would remain 22 years old and double-glazed with a U-value of 1.3.

Sorry, mushroom head locks do not prevent break-ins; they only delay them by about 10 seconds. Therefore, I would avoid retrofitting and replace the windows gradually.
Additionally, the window specifications must be compatible with the building’s insulation. Simply installing something without consideration does not make much sense.
Best regards in brief

We also still have drilling and cutting out the window in our repertoire...

Regards, YvonneI’m talking about break-ins, you’re referring to prying.
By the way, when upgrading, only as many locks can be added as are already installed. But I’m not an expert in that.
My source is actually my professional experience as a private investigator. It’s not just about swinging a paintbrush 😉
