If I didn’t understand the reason behind it, I might think the same.

What is the difference between 2 cm (1 inch) and 4 cm (1.5 inches) insulation? On paper, in calculations, it might not show a measurable difference in costs, or just try not to open the window for one day.

It’s not about heating or construction costs, but about the difference between mold and no mold.

And that’s exactly where the 2cm (0.8 inches) make no difference at all.

Do you know that? That was exactly the point — it’s not something you can just roughly estimate. But as was nicely said earlier: to each their own.

Mold occurs when heating and ventilation are done incorrectly. Some corners are more critical than others.
On construction sites, a centimeter (0.4 inches) is not a reliable measurement. I don't even want to imagine in which areas some people might have cut corners. So, I wouldn't worry about that either.

Just because some shortcuts are sometimes taken doesn’t mean you should skip a proper calculation. Of course, if you prefer to build like it was done 50 years ago, you don’t need it.
