Hello everyone.
I am new here and not a professional. I only have DIY experience. However, I have a question that has been bothering me for a long time. Here in the USA, more and more buildings are being insulated on a large scale with polyurethane (PU) foam. Could you experts tell me if this is effective, and how it is handled in Germany? You are familiar with the American construction method: wood framing, drywall (gypsum board) on one side, particleboard on the other, and depending on the budget, either plastic cladding or 5cm (2 inches) thick brickwork. I have heard that this method brings some issues:
1. Temperature differences between summer and winter
2. Environmental impact
3. Health concerns
4. Efficiency
5. The "breathability" of the wall
6. Cost
Opinions especially differ regarding the cost… The entire equipment package (trailer) costs about $35,000 USD. The chemicals probably don't cost much, and honestly, 1 square meter (about 11 square feet) is insulated in 10 seconds.

This can also be produced by spraying in a factory and has good insulating properties. There, it is only cut into panels. You might want to check Linitherm.de’s website to see if that helps you further.
Otherwise, you should consider the use of vapor barriers and airtight membranes.
