Construction company wanted in the Ingolstadt - Munich area

However, the thinnest version with external insulation makes no sense, as it destroys the vapor diffusion property of KlimaPor.

Only fools reduce sums. That this could also apply in essence to adding a colorful salad of building materials to a wall structure with the sole aim of achieving a specific U-value is often overlooked by the Excel-believing wall structure designers. Füsick is not a particularly trivial science

I would also prefer a reasonably pure material wall over a Wolpertinger sandwich from the lab

We had an appointment in Poing with Lechner Massivhaus about a week ago.
They are currently building the new show house. The house is being fitted out inside, so we were actually still able to see the shell. It was a hellishly hot day and inside the house it felt like 15°C cooler. We really like the building material KlimaPor, very much! However, the thinnest version with external insulation doesn’t make sense because it destroys the vapor diffusion property of KlimaPor. If anything, you should go for 36.5 or even 42 cm wall thickness for the exterior walls. We have another appointment soon to get a more detailed offer for the "model house". I can keep you updated.
Our contact person made a good first impression. I’ve experienced different things before… One competitor shot themselves in the foot. I don’t need anyone who self-praises for 2 hours...

Technical fact: A fuel cell is installed as the heating system in the show house. I will take a look at it when it’s finished. When I asked where the hydrogen is supposed to come from, I was told that natural gas is converted. So basically power to gas but backwards.
