Hello,
recently we have started building our own house. That means we have a plot of land and are looking for a suitable house.
This week, we spoke with several construction companies. Regarding the exterior wall of a solid masonry house, we received different information: One company said that a 36cm (14 inch) Poroton brick with 2cm (0.8 inch) thermal insulation plaster meets the thermal insulation requirements. Another company told us it must be a 20cm (8 inch) Poroton brick with 10cm (4 inch) expanded polystyrene insulation.
We tend to prefer the 36cm (14 inch) Poroton brick with thermal insulation plaster, but the differing statements have left us uncertain.
What is better in terms of insulation values? What are the advantages and disadvantages of both options? How do the costs compare?
I wish everyone a great weekend and hope for some advice to help with our decision.

Hello,
Here I would really think carefully again...
...Low heating costs already start with the choice of the building site! .....I have already mentioned that this is my first time building, so I have to deal with many things and am basically a beginner. I do not claim to know everything. And I have thought things through. Now I wanted to read opinions here in the forum and instead I receive advice about my concept.
If I were building in Africa, I probably wouldn’t have to worry so much about heating costs. But the plot is in Germany.
Dear Euro, you are probably right from your point of view, but your answers do not help me at all.
Kind regards
